Why is it so special to rob the human brain? So, it came to mind, the great wine - but not the greatest of the most important. You, obviously, chuli, that your brain is made up of 300 billion neurons - but did the number come from the stars and it looks like it’s on aphids showing other living things?
You may think, you know, there is a great chance that you have been seriously misinformed about why your brain is more specific, the brain of other living beings on our planet. The axis to you is the greatest myth of the human brain.
Myth 1: The human brain has a hundred billion neurons
Neurony is the fundamental life-cycle of the nervous system. CI Specifіchnі Klіtini, Vidokodіbnі Vіdrostkki Poing on Boki Boki і stitching zlya zdovstnikov Sousіdnіh klіtin, molding the magnitude of enectrichnaya ta khimіchnu merry, yaku є our brain, the ones of іnformakіu about our sweeping, giving our diyi vіdpovy to the Central Self, control our unfamiliar physical functions. Our neurons themselves allow our brain to make different things more efficient and more efficient, no matter how many created machines.
Since the number of cells play an indispensable role, you can admit that the scientists have a couple of ideas about how many neurons themselves are stacked between us; And so many times we thought that it was so. Scroll through a handful of neuroscientists, a couple of scientific reports and scientific journals, and you will see how many people signify the number of neurons in the human brain with a beautiful round figure of one hundred billion - and start to roar without a message.
Why without a message? According to the opinion of the neurobiologist Dr. Herculano-Hauzel, it seemed that the annual direct estimates of the total number of neurons in the human brain did not work until 2009, if that team won the brains of some recently dead people, they brought them to the laboratory . , It is called "isotropic fractionalization" Herculano-Hauzel and his team cut the skin brain into a homogeneous emulsion in what looked like "brain soup" (these words, not ours), took samples from that soup, improved the number of neurons in the skin sample, extrapolyum to take away the total number of neurons in the skin brain “cake”.
We have shown that the average human brain contains approximately 86 billion neurons,” Herculano-Hauzel said in a recent podcast to Nature magazine. Let's keep going: Joden's brain, which we have reached at the same time, not having avenged a hundred billion clitin. I want to know that the difference is not even greater, but 14 billion neurons in the brain of a baboon, for example, or maybe half of the neurons in the brain were on fire. Also, it's really quite a decent price.
Myth 2: The bigger brain is the smaller team
How can you get away at once with a pack of a few close-disputed views of living things, open up their cranial boxes and scratch out the sounds of the brains, you, better for everything, will mark the correlations between the absolute size of the brain and the cognitive vitality of the creature. Among the savtsіv for example, primati (on the kshtalt of us) and whale-like (on the dolphin’s eye) weave more bellies, lower, let’s say, comahoides (on the kshtalt of the murahoid), and mum those who can recognize more as proportionately large roses. Based on that caution, you can shy away from thinking that brain size is a good predictor of cognitive ability.
The proteo admonition “Bigger means better” is broken, as only you start to break up the specialties of different species. Cows, for example, may be more fat, less practical, be some kind of mavp, but even if they stink, they are not more (more) good at hooking up, cows are practically unambiguously less rosy, less more (not all) "less brainy" primates. In a similar rank, the brain of a capibari (a water pig, the largest rodent on Earth; approx. mixednews) can weigh over seventy grams, but the cognitive strengths of the capuchin will grow pale in the head of the capuchin, the brain will take ten grams.
Reasonably, for the purposes of our discussion dedicated to human brains, the most promoted proof of the fact that “bigger does not mean better”, will be the equalization of our brain and the brain of the greatest savtsiv, such, for example, like a whale or an elephant. The average human brain is about 1200 grams, and the elephant's brain is four times larger, and the largest brain is in the sperm whale, and the weight is 6800 grams.
With a brain, which is important for six times more for people, why did the sperm whales do not support their own people?
Myth 3: The brain of a person can be the largest expansion to the expansion of the body
This myth has come down to us since Aristotle’s hours, who wrote in 335 years before ours: It’s easy to eat pasta with qiu, so you can try to explain the difference between the brain and intelligence of, say, humans and sperm whales. In our days, a lot of people corystrate with approximately the same explanations that Aristotle, to reconcile himself - the link between the brain and the brain is not in an absolute vase of the brain and the body.
It is important to remember this logical language, and you will see that you are giving us one more inaccurate picture of the same thing, which we truly infer from nature. Thus, the spіvvіdnennia medulla to the body in humans is evenly equal, say, with an elephant (nearly 1/40 against 1/560 vіdpovіdno); but it’s more similar to the same spiving in a large mouse (also 1/40), and to induce less spiving, as you can see in some small birds (1/12).
In order to improve the substitution of the basic brain spacing to the body, we conceived a folding system of assessment, like the “encephalization factor” (EQ), which mimics the brain sparing and the size of the body of a creature compared with other creatures of approximately the same size. In my opinion, EQ is not only wrong with the fact that the expansion of the brain may tend to increase over the increase in the expansion of the body, but also those that the expansion of the brain does not change proportionately increased body.
If the factors of encephalization in different creatures were equaled, the stench revealed that this factor is greater in people, lower in any other living being on our planet.
Myth 4: The brain of a larger size will compensate more neurons for a smaller brain
And yet, the factor of encephalization can take revenge on one’s own mind, for one simple reason: a larger brain does not necessarily take revenge on oneself more neurons, a smaller one is a fact that turns us to myth number one and nourishes a certain number of neurons after all human brain is formed.
Vcheni, zrozumіlo, dosit for a long time to know that the expansion of the brain of creatures can grow in different species. Ale, until recently, prote, more research was allowed, that the density of neurons different classes of creatures. However, the reconciliation cannot be far from reality.
Press, schob zbіshiti This myth was freely victorious by Dr. Herculano-Hauzel and his team, if the stench victorious all the same method of brain soup for mitigating the number of neurons in the human brain, in order to determine the total number of neurons in different species of ssavtsiv. The results of their investigations, as of now already published in a series of tweets, demonstrate that different types of savants follow the various “rules of rozrahunka”:
Mіzki primatіv, as it appeared, increase in the number of neurons in them; If you compare one gram of great primate neuronal tissue with one gram of lesser primate, you take away approximately the same number of neurons.
Mizki grizuniv, from the other side, like z'yasuvalo, zbіlshuyutsya near the world shvidshe, how to fill new neurons. As a result, more rodents tend to mothers have a smaller number of neurons per gram of neuronal tissue, lower other varieties.
Mizki comachoid behave like a combination of the brain of grizzlies and primates, with the bark of the brain, as it increases in size, the number of neurons increases (similar to grizuniv), and the brain, the spiding of the brain increases in some linear (similar to primate).
The end of the vysnovok should sound like this: among grizzlies, comahoides and primates, a brain of primates of inducements on the basis of the most economical principle, which maximizes the available space. Dr. Herculano-Hauzel writes: A tenfold increase in the number of neurons in the brain of a rodent means a 35-fold increase in the brain itself; for equalization, also a tenfold increase in the number of neurons in the brain of a primate means an increase in the size of the brain only eleven times.
The brain of a hypothetical grizzly bear with 86 billion neurons (similar to a human brain), weighing thirty-five kilograms - which in a lot of times overturns all the parameters of any living being.
Chi є the human brain is special?
Іsnuє kіlka vysnovkіv, yakі it is possible to work out the number of chotiri from the rozvіnchannya myth.
Perche, Vono demonstrates that the visible expansion of the brain (navit with the improvement of the encephalization factor) cannot be victorious as the best measure of the number of neurons in different classes of creatures. More than that, it’s really worth bringing up the visnovka, which is the expansion of the brain, the expansion of the body, and the links between them, which are not sufficient indicators of cognitive health, and which similar allowance should be more focused on the upper number of neurons, which is the most important.
And in a different way Tse v_dkrivaє us two dosit counterintuitive facts about the human brain. The first one is that our brain is called unique by the singing world. Vіn mіstiti 86 blіardіv neuronіv, аlе tse аrе thаt number, yоu сhіkuєte tо know (on the basis оf thе rule rozrahunku primatіv) іn thе brain іѕ such a rozіru; If you enlarge the brain of a chimpanzee to the size of a human brain, you will reveal in a new way the very number of neurons.
And the other believes in confirming the fact that something in the human brain is truly unique.
Dr. Herculano-Hauzel explains:
First, the brain of a human being grows according to the same rules that the brain of primates: a greater economic principle in pairs with grizzlies allows you to pack more neurons in an accessible space, more neurons in the brain of a grizzle, and it’s possible to be alive in the brain istoti. Well, let me tell you. In a different way, our camp of the middle primates as a volunteer of the largest infertile brain guarantees that we can take on the largest number of neurons from among the primates, so as to shy away our contribution to the formation of soundness and behavior in the whole.
Those, in a way that our unprecedented number of neurons in the brain will go down with such speeches, as our genetics and the brain structure, will give the results of the most advanced cognitive vigor on our planet, yet to be known.
For example - like the brain of a chimpanzee, as if it were possible to increase it to a human level, how could we shave our cognitions to a level, what do you see for ours?
Otherwise, "not yet developed" nutrition - how to improve the number of our neurons and the "rule of rozrahunka" with other types of savts, and especially with those who can have a larger brain size? As of today, the exact number of neurons in either elephants or cetaceans is not known.
Speech on intellectual rіven? How much do you think the brain of a child is grown up? Why do wines change at rosemaries at the old process? Ask - a large number ...
Also, how important is the center of rozum's activity of a person?
Otzhe, in order. How important is the brain of a person in the middle? Based on scientific findings, the body of the central nervous system, which consists of a large number of nerve cells, becomes 1.1 to 2.0 kg (in addition, 2% of total
Representatives of the human state have a mass of gray speech approximately 100-130 grams larger, lower in the female half.
Intellect proportionate to the vaga?
How important is the brain of a mature person? For a person, the average statistical indicator becomes 1424 grams. The record vaga bula was fixed at I. S. Turgenev - 2012 For povnyannya: Ludwig van Beethoven's brain was built in 1750, V.I. Lenin - 1340 rubles, Sergiya Yesenina - 1920 rubles, D. I. Mendeliev - 1571 These ostentatious people create a theory about those who, on a par with the intellect, pour in the ostentatious ostentation of a simple speech. The brain of a genius can appear much less, lower than the brain of a human being, endowed with broad intelligence. It has been brought scientifically: to the rіvenі іntelekt vpivnі nіlіnі іlіnі іnі іnі organ of the nervous system, in yіkіkh the key role is played by the frequency of degeneration of neurons and kіlіkіsnі zv'yazki between them. Like a Yaskrav butt: the largest brain of a vag 2850 grams laying on a perplexed people.
How much do you care about the brain of a modern person? which borrows practically the entire empty cerebral part of the skull and takes its form in the process of growth and development, evolution: in the 19th century, the average weight of the people was 1372 grams, which is significantly less than the current values. For the representatives of the beautiful state, the greatest show is the vaga of 1565, the least - 1096 (before fixing the 31st woman). In 1956, the woman herself, the 10-year-old girl Marilyn Vos Savant, a bagger from the state of Missouri (USA), managed to pass the best test in 1956 with a score of 228, which was a kind of crossover to the Mega Partnership, which unites people with the most outstanding IQ indicators.
Is the head of the brain proportional to the head?
Masses of gray speech are also deposited in the life of people. In a newborn child, the average indicator is 455 grams. How old do you need to be? The human brain has ceased to be a constant size.
From the moment of the people's growth until the 27th century, the speech grows, and then it begins to change. Skin 10 years of yoga is shortened by 30 years. Until old age, the number of signals in the nervous system also decreases. From an average indicator of 288 km / year, the won will change by 15%.
Efficiency of victorization of the brain with rozumovіy diyalnostі
How to care for the brain of a person - it’s wise to understand. Blame food: why is speech as victorious as possible? I have a thought that the life of a human being has only 10% of his brain. Chi so tse? This thought is ambiguous, but more scholars are smarter than the wigs, so that I can increase my potential. For the sake of the simplest leader, speech is activated in all of its widdles.
As soon as people start to think, the amount of energy saving that enters the body reaches a figure of 25% at that hour, as in a calm, Syrian speech, no more than 9% of energy is required. Mozkova diyalnіst, scho aktivіzuєєє, vymagaє dodatkovogo sour eating, scho zmushuє mozok take away from the body practically yoga tretin.
Trim the brain in the form
Trim the brain in the form to help regular sports activities, like b zbіlshennya capillaries. And at the same time, it ensures the maximum intake of sour and glucose into the body. The most effective are the rights, the trivality of which is not less than 30 quills per day.
In the most effective way, the development of the brain is important to take on a new, unknown activity, and to inspire intercourse with people, as if turning over for the intellect of the mind. The lighter the human being, the less emollients for the ailment of the brain, even the rozum activity of the vibration of the additive tissue, which replaces the damage.
Trochs about the brain of other living organisms
How to care for the brain of a person - it became clear from what was written. And yak yogo vaga, for example, at the elephant?
In pairs with humans, the brain of representatives of the largest savts on the planet is 2 times larger, and it is important to weigh 4 to 5 kg. Once again, I confirm the theory that the rіven іntelekt and vaga sіroї speech are found in different flats.
The biggest creature that can be classified as a class of savants is important. Yogo average weight is 150 tons, and dozhina is 30 meters. The weight of the brain is 9 kg for the 1st increase to the weight of the body: 1 to 40,000.
Then, long-dead dinosaurs, which reached a height of 9 meters, had a brain the size of a hairy mountain and weighed only 70 grams.
A person respects himself with the most intelligent nature on the planet. How can I lie in my brain? How much "vitrate" for the body to think and how much time is needed to think in thought?
Por_vnyannya rozmіrіv the brain of a black whale (levoruch) and people (right-hander)
The middle vaga of the human brain is 1.4 kg. The brain of an elephant weighs 5 kg, and a black whale - 6.8 kg, and a sperm whale - 7 kg. Spivvіdnoshennia masi brain and masi body, so the ranks of the cerebral index, in humans, are not the same. Brain becomes close to 2% in the mass of the human body, in hummingbirds it becomes 16%, in the comatose bear - 10%.
The expansion of the brain in different people can be significant, and the great brain is by no means a sign of genius. For example, the head brain of Albert Einstein is important in 1230, and the head of the head brain (2850) was a patient of a psychiatric hospital, who suffers from idiocy.
Think about the majestic energetic vitrates. Borrowing a total of 2% of the weight of the body, the brain in the inactive state gets 9% of the energy that comes. And as soon as a new one has a hedgehog to think about, you start to save a quarter of energy and a third of sourness to come.
After the intellectual work of the body, the need for repairs. The head brain is resurrected for the morning before, the lower hour, stained for thought. Tobto after 4 years of active intellectual work may be 12 years of complete intellectual negligence. Don't forget to take care of your neurons.
The birth of the new is born in the middle of the old - this is the law of nature. We are evidence of the birth of a new race of people. Dekhto call them "sunflowers". In other words, all the people, as if they were moved in a splendid way, take energy for life.

The vcheni doslіdzhuyut that signify the spіvvіdnoshennia obliging the brain to obliging the bodies of living things on Earth. So the stench z'yasuvali, who has the creature's best brain. It seems that among people there is a record holder for a vagago brain.
Who has the biggest brain to body?

It would be possible to indicate the spontaneity and the middle of the spineless, the protein of such a brain does not stink, then the nerve nodes or ganglions. How to calculate the spіvvіdnoshennia, having broken the mass of nerve endings from the mass of the body of the spineless, we see that the record holder is a goosebump. Spivvіdnoshennia in a new order 14.The yakby of a man with spivvіdnoshnennia 14, like that of an ant, the head would have weighed no less than twenty kilograms, and the bula would have been about the highest times more. Tim is not smaller, the brain of an ant is forty thousand times less than the brain of a person with a equal number of clitins, for which they add up.
Vcheni conducted research and investigations, to understand, chi maє goosebumps rozum. It was clear that these miniature comahi zdatnі zagalnyuvat and synthesizing information, like the stench was taken away.
Ants can learn, the stench grows step by step, which confirms their folding social appearance. And if you look folded, then for more than an hour you will get goosebumps on the head. The nervous system itself does not allow murah to be taken in by intelligent creatures. Through those that the brain of the coma is composed of five hundred thousand neurons, it’s not good to think. Low vchenih vvazha, scho middle murah іsnuє rozpodil brain between members of the colony. Tsej rozpodіl can porivnyat zі z'єdnannyam kom'yuterіv y vglyadі Іnternet on vyvіshennya sevnih zavdan.

It is marvelous such a zbіg - similar spіvvіdshennya in humans is the same, like in Ribi Mormirus or Ribi-elephant. Vono dorivnyu 138-150. In the middle of the rib same, the riba Mormirus has the greatest spivvіdshenie masi brain to її tіla.
After investigating the cirque of spiving among primates, it was found out that it is most common not among people, but in the mavpi of Bilin or Saimir. Such spіvvіdnoshennia in which primate to become 117.
Creatures with great minds
The followers, following the watchfulness of dozens of different species of creatures, killed the wisps, which those, whose absolute obligation to the brain is greater, better control their behavior. It is not about the mass of the brain, but about the yoga spiving with the volume of the body. Tsikavo, scho mavpi, wolves, m'yasoidni dogs showed a garne of self-control, and the axis of an elephant showed nasty results.You can evaluate the brain for the support of yoga oblige to oblige the body, but, according to the size. Record holder kіlka. It seems that the elephant has the brain of the largest mass among the terrestrial creatures. Nearly five kilograms - styles to take care of the brain of the Indian elephant.
The record holder for the middle of the living planet behind the brain is the whale Physeter Macrocephalus. The brain of this creature can reach nine kilograms. However, if you calculate the amount of the brain to the body, then we will have 140,000. Apparently, the blue whale is richer than the sperm whale, the proteo brain is smaller and more important is six kilograms and weights of grams.
Another volodar of the great brain is the white dolphin. One’s brain can weigh two kilograms three hundred and fifty grams, just like a dolphin’s bottlenose dolphin can weigh only one kilogram six hundred and thirty five grams.
The living essence of the planet with a great brain is a person. In the average Yogo, the brain is important from one kilogram of twenty grams to one kilogram of nine hundred and seventy grams.
The largest human brain
Vaga the brain of a person to lie rich chinnikiv. In other words, a man's brain is larger than a woman's by about one hundred and fifty grams. There is no serious difference in the vase of the brain among other races.
Our ancestors' brains are much smaller, ours are lower. Vaga significantly changed, if the first primitive person appeared. The brain of the Pithecanthropus did not exceed nine hundred cubic centimeters, and the brain of Sinanthropus was close to a thousand two hundred and twenty-five cubic centimeters, having thus overtaken the brain of a modern woman. It seems that the Cro-Magnons have a small brain, the volume of which is one thousand eight hundred eighty cubic centimeters.
Today, the brain of Europe becomes close to a thousand and a hundred and forty-six cubic centimeters. You can make visnovok, so that the skin of 200 years of the brain “shrinks” by one cubic centimeter. I would like to be sure that the change of the contract is not carried out to the fall of the intellect, but rather to the reduced design.
It seems that Ivan Sergiyovich Turgenev's brain was equal to two kilograms and twelve grams. It would be possible to take his brain to the largest, prote, for some individual, who had lived more than three years, his brain became two kilograms of nine hundred grams.

The brain of a person is important from 1100 to 2000 g, which becomes close to 2% of the weight of the body. With the weight of a woman and a human brain, the difference is that the strong half of the brain is “important” by about 100-150 grams. Zgіdno s dolіdzhennym vchenih, vaga mozku also lie in the vіku vіku people. For example, a newly born child has a brain mass of 455 grams. How important is the human brain? Let's try to get to know each other's food.
How important is the brain of a mature person?
The brain stem consists of impersonal nerve cells and is one of the most important organs in the body. Іsnuє dumka, scho rіven іntelektu lyudiny lie in the masi її mozku. However, no more, lower myth - the brain of a genius as a whole can appear smaller, lower the brain of a person of low rosy intelligence. To finish the protezhiti "dimensions" of the brain of the rich of the great minds of people. Later, we go back to statistics, that is similar to the mass of the brain in such prominent features, like:
- Walt Whitman - 1256
- Lenin - 1340
- Stanislavsky - 1505
- Trotsky - 1568
- Mendelev - 1571
- Pavlov - 1653
- Beethoven - 1750
- Yesenin - 1920
- Turgenev - 2012
- Byron - 2238
Like a bachimo, the manifestation of the talent of special talents does not lie in the vіd vаgi of the human brain. It has been brought to the attention that the okremі dilyanka of the brain is poured into the brain - “Sira speech”. And here, in its own right, the density of the distribution of neurons and the number of connections between them plays a vital role.
Too much illness can provoke an increase in measles in the brain, which is indicated by yoga mass. The largest brain was fixed by science - 2850 grams! Schopravda, the leader of such a “unique” was a half-witted person.
Tsіkavy fact: representatives of different races and nationalities make different brains. For example, in Belarusians, the average brain is 1429 grams, in Russians - 1399 grams. If you equalize the mass of the brain of a black-haired American (1223 g) and that of an “average statistical” German (1425 g), then the difference between the pokazniks stock is 202 grams.
The brain of a person is important from 1100 to 2000.
Australians have the lightest brain - 1185 grams! Trochs "important" brain in Asians - Koreans and Japanese (1376 grams and 1313 grams in general).
Slid designate, scho vaga brain ceasing to be a static value. From the age of up to 27 years, the brain “grows” at the vase, and then it gradually decreases, but steadily decreases. For the skin of 10 upcoming fates, a person spends 30 grams of the brain!
How much do you care about the brain of an elephant?
The average weight of the elephant's brain is from 4000 to 5000. As if it were equal to the human brain, then the representative of the largest savts of the brain is twice as important. As it was brought to a scientific conclusion, the rіven іntelekt cannot lie due to the size of the brain - otherwise, the "crown of creation" on the planet would be not a human being, but an elephant and a whale.
Elephant brain mass - 4000 to 5000 grams.
What criterion influences the potential level of intelligence? Tse spіvvіdnoshnja masi mozku іz zagalny vаgou body. Watching out for different types of creatures showed that creatures with a greater display of buildings are better able to control their behavior. In humans, the spivvіdnennia of the vag of the brain to the mass of the body should be 1: 40, and the axis of the elephant cannot “boast” with such successes - for these majestic savts, the figure should be 1: 560.
How important is the brain of a whale?
Masa whale brain sagaє 9000 grams.
Blakitny whale is the largest creature class of savtsiv, as if it had been founded on Earth. In fact, the whale's body often exceeds 30 meters, and the body - over 150 tons.
The weight of the brain of this water "record holder" reaches 9000 grams, and the ratio of this indicator to the head of the body becomes 1: 40,000.
How much do you care about the brain and heart of a blue whale?
We can mention the fact that the mass of the whale's heart becomes 600 to 700 kg, and the average brain weight is 6.8 kg. Yak bachimo, whale's brain lying behind the heart about 100 times. Why does a whale have such a “great” heart? On the right, in the fact that, with the transport of blood by the vessels of such a majestic rich-toned body, a small heart would hardly fit b.
Pivnіchny dolphin bіlukha є volodar of the great brain vaga 2350 grams. And the axis of yoga "zіbrat" dolphin afalіn masa brain - total 1735 grams.
The human brain is a unique vitvir of nature. The age of the sun in the body of the body part of the brain becomes less than 2%, and for restoring in the state of the “calm” the body needs at least 9% of the energy to reach the body. What else to say with the activity of rozumovyh processes! One day a person begins to “strengthen” to think, the rіvennja spozhivannja energії once zrostaє up to the sign of 25%. Until then, increased brain activity will require supplemental sour eating. So it’s time for the completion of logical tasks, or writing our brain “takes” from the body up to a third of all the sourness that comes.
Now we know how important the brain of a person is by itself, as well as by growing to the brain of some creatures of the class of savtsiv.
Vaga mozku normal people are counted from 1020 to 1970. The brain of a person is important by 100 - 150 grams more, the brain of a woman is lower. There is no serious difference among the okremy races. At every time, non-Europeans sit in a place. The middle brain of African Negroes is 1316, Europeans - 1361, including Germans - 1291, Swiss - 1327, Russian -1377 grams. The head of the brain of the Japanese is 1374, and the Buryats - 1508 grams.
And how to recognize how important the brain of our distant ancestors is? The size of the brain can be determined by the dimensions of the skull. The largest representative of today's human-like mawp has a small braincase - 440 - 510 cubic centimeters. Under the hour of transition from the great mavpi to the primitive person, the brain became significantly larger. In the pithecanthropus, the veins were 750 to 900, in the synanthropus they increased to 915 - 1225 cubic centimeters, so that they overtook the brain of a modern woman. The volume of the skull of the African Neanderthal reached 1325, and the European - 1610 cubic centimeters. Nareshti, Cro-Magnons were, in a right way, head bats with a brain volume of up to 1880 cubic centimeters.
Dali the size of the brain went into decline. Excavations in ancient Egyptian pyramids make it possible to repair the skulls of the pharaohs in a stretch of a thousand thousand. For 2000–3000 years from the reign of the first dynasty of the pharaohs to the 18th dynasty, the capacity of the skull fell from 1414 to 1379 cubic centimeters, about 200 cubic centimeters per cubic centimeter of skin. And in Europeans, the brain significantly "shrinked" for the rest of 10 - 20 thousand years. Yogo obsyag at the modern European to become at the average 1446 cubic centimeters.
Maybe, have you been smart for us for a long time? It is unlikely that they would like to be prominent thinkers: even if it was necessary to reach the whole need with their mind. I would like to understand that the change in the brain growth and the improvement of the yogo design are not accompanied by the fall of the intellect.
The middle creature has the biggest brain of a whale. The blue whale has 6800 grams of wine, about five times more than a human one. The head of the brain of the Indian elephant is close to 5000, the white dolphin - 2350, the bottlenose dolphin - 1735 grams. Por_vnyannya nachebto is not at the expense of people. Ale needs to be protected like a vaga brain, and th expansion of the under-ordered yoma of the state. Zichayny whale - tse 30 tons of fat, brush and meat. An elephant is worth close to 3 thousand, a white whale - 300, and a human - a total of 75 kilograms. In our country, 1 gram of the brain commands 50 grams of body, and in an ordinary whale - five kilograms, may be 100 times greater than the state. If you take giant whales with a 100 - 150 tons carload, which are eaten in the ocean, then they will get over 20 kilograms of body per gram of brain - a great attraction for nerve cells.
It turns out that with our brain on the right, it’s easier nowhere - the more “serious speech”, the better. Prote for such a logic, elephants become a dominant species on the planet, and not humans. Luckily for us, a larger brain expansion does not mean greater efficiency, but better cognitive strengths, but in some cases it brings on the bad. Concepture publishes a translation of Nautilus articles, in a way that is familiar from the nervous system Susana Herculano-Huzel reveals about those why our brain is the best example.
Masa brain that mislennya
For a long time we thought that it was the height of the cognitive zdіbnosti among us creatures. Ale z deyakah to finish important points of dawn, such a dense nomination is by no means synonymous with "the pinnacle of evolution." As having marked Mark Twain in 1903, it is assumed that evolution is a fundamental path that led to the people, as far as the rest of the world, it would be so foolish, as if to think that the only method of life of the Eiffel.
Moreover, evolution is not synonymous with progress, just change the hour. And people are far from being the youngest, who has recently evolved looking. For example, over 500 new species of cichlids (family of ribs) in Lake Victoria (the youngest of the great African lakes), appeared from a silent feast, like a yogo hole was first filled with water 14,500 years ago.
However, it is truly unique in our brain that it is possible to rob him of the age of the mind, to inspire him about his devices, which is the reason for blaming the hypothesis about the role of yoga Verkhovensky in relation to other types of the brain. Even we ourselves will see other creatures, and do not stink us - a vago argument against the malice of the special nature of the human brain.
The mass of the brain falls into the thought that it is obviously a solution to the riddle about those, which brain is the most attached to a guilty thought: if the brain itself can be robbed of knowledge and knowledge, then the more yoga you have, the more cognitive strengths you have. But here it’s easy, as it seems, not to commemorate an elephant, not only figuratively, but literally: an elephant is a stature, whose brain is bigger than a human, but with whom wines it doesn’t demonstrate such a complex behavior, like me.
In addition, putting a sign of equivalence between the great expansion of the brain and the development of cognitive strengths, we admit that all the brains are “broken” however, so that we see a similar development of the development of the brain and the number of neurons. But my colleagues and I already know that the brain of different species is "broken" differently.
The primacy may be clearly superior to other savants, like vinicla zavdyaki zbіgu evolyutsіnyh obstavin, scho allowed more "economically" to increase the number of neurons in the brain without the need for a significant increase in the average size of the clitin, which will develop in.
"Hello beauty!" Since the beginning of the 1960s, psychologists have wondered about the power to recognize oneself in a mirror as a sign of intelligence and self-confidence.
Also, the crime of the mind in the brain of different species, we also consider the number of neurons in some of them, to this we can cause a greater difference in cognitive health, not just in the brain, which is rude, but in the number of neurons.
Until then, this hypothesis can be tested practically. A large number of neurons has become an attacking good option for nutrition to improve the attachment of the brain to the mind, independently from the expansion of the brain. Even though the very neurons are those that give the cob to their cognitive activities, then the greater the number of neurons in significant cognitive developments. Chi wrong?

Alex, an African Syrian parrot, the master of such a bool, psychologist Iren Pepperberg, having learned to use words that symbolized objects, and chimpanzees that were on fire, although they cannot articulate sounds for anatomical reasons, learn to speak for help with moving gestures.
Chimpanzees can master the ієrarchіchіchі sequences: stinks play at the game, de їm it is necessary to stick around the squares in the top order according to the numbers shown earlier, and stinks win the gris so very good and so very fast, like people are already trained. Chimpanzees and elephants can spivpratsyuvati one with one, sob distance їzhu, as the skin of them alone is inaccessible. Chimpanzees, as well as other primates, demonstrate the ability to evaluate the mental state of others, but it is necessary to change the mind before deception.
Navit birds, let's go, may be aware of the mental state of other individuals: for example, magpies can defiantly catch zhu in the presence of outsiders, and then, if outsiders come, they will fight and catch it in another place. The chimpanzees were on fire, the elephants, the dolphins, and also the magpies showed signs of what the stench was aware of at the mirror, like the stench was whipped to look at the marks, like the investigators put on their heads as part of the experiment.
Can the brain of an African elephant really have more neurons?
We guessed about the fundamental conclusions, which confirm the cognitive vibrancy of the species, which are growing in our minds, but so alone, caution cannot be the basis for interspecies conflict, as we need to carry out, as we want to know such allows you to achieve cognitive feats that are inaccessible to others. And here we are dealing with another problem - in fact, the largest at this stage: how to reduce the cognitive strengths of rich species and grow in such a way, so that you can take away their skin significance, so that you can equalize with yourself.
In 2014 rotsі Bulo held doslіdzhennya, yak fokusuvalosya on samokontrolі (kognіtivnoї zdіbnostі, yak ґruntuєtsya on prefrontalnіy, asotsіativnіy chastinі measles pіvkul head mozk) on prikladі dekіlkoh vidіv tvarin - mostly primatіv, Ale takozh drіbnih grizunіv, sobakopodіbnih hizhakіv, azіatskogo elephant that deyakih ptahіv .
The results of the study showed that the values that most correlated with the correct behavior during the test for self-control, were the absolute obligation of the brain. Behind the blame of the elephant, which, without regard for those whose brain was the largest among the "participants", appeared not in the mind of vikonaty as a follow.
The reasons for this can be guessed richly, such as “Yoma just didn’t give a damn about the old day”, to “Yoma should have angered the elders of the old day.” (I would like to think that the reason why the mawp is so important to teach diyam, as if they are already quickly mastered by people, is those who mavpi consider themselves an image of the obviousness of the task: “That’s right, you want me to "Give me something cooler! Let me play at the video game!")
Susana Herculano-Huzel has served the purpose of working the human brain in such a special way, allowing you to perform richly complex operations, lower ti, zdіbnosti to such demonstrating creatures. Photo from the ledge for TED.
In my opinion, the best way to explain the bad results shown by the elephant is that the African elephant simply does not have all the prefrontal neurons in the cerebral cortex, which are necessary for the completion of the task of self-control (like ti, z zakimi in the experiment).
Osskilki Mi Visnali, Shaho Mіzki Primatіv І Grizunіv "Zroblenі" in the riznaya І Majut Rizna Kіlkіt Neuronіv, Northy Yakscho ї ї Romіryi can be poring, mii rushed out of the logishness, Yak Svіdchilo, Scho Moskov of African Elephant, Yakschko Vіn worshius on Kshtatt Mosku Grizunіv, the mother is responsible for more than 3 billion neurons in the cerebral cortex and 21 billion neurons in the cerebellum, among our 16 billion and 69 billion, apparently.
On the other side, like the brain of an African elephant, like the brain of primates, then the guilt is to blame for the neumogeneous number of neurons: 62 billion in the cerebral cortex and 159 billion neurons in the cerebellum. Ale elephants, obviously, are not seen either before primates, or before rodents; the stench of Afrotheria (Afrotheria), like and a sprat of small creatures, such as the dove-whisker and the golden mole, which were already preserved earlier, and as a result of their confinement, they made a visnovka, whose brain functions even like a grizzly's brain.
Need to spend 100,000 dollars on stained glass, how will the butcher's bottom come in handy?
Otzhe , Is it true that the brain of an African elephant, which is more important for ours, avenges more neurons? If it turns out to be true, then my hypothesis, as it seems, that the cognitive viability of the values, similar to the number of neurons, will be challenged.
Ale Yakschko to show up, Shaho Lyudsky Mozoka Maody Kilkіt Neuroniv, Nіzh Mozoks African Elephant, Scho knowingly flimsy for Romіrs, then Tse pіdtimaє Moє Squeezed, Scho Niproste's cognizes of Kogn_ybniki Lyudsky Lyubility є Primіtn Neuronіv's Number of Mosku, Yaka Bіlsh. in one form, independently of the characteristic of the brain. Zocrema, I figured that the number of neurons in the cerebral cortex of a human would be greater, lower in the cerebral cortex of an African elephant.
My admission was rooted in the logic of cognitive science, for a long time they voted the cerebral cortex (or, more precisely, the prefrontal part of the measles of the brain) as a single "residence" of svіdomostі, and also: the abstract mission, the plan of the day has been adopted.
However, practically the entire cerebral cortex is connected with the cerebellum with loops of the ligament, so that I will “attach” the pieces of measles information and the cerebellum one by one, and more and more, they gave an idea that the brain is taking part in the cerebral cortex brain cognitive function. Also, we can say that these structures work in tandem. I skіlki і structures at once may have the largest number of neurons in the brain, cognitive zdіbnostі vinnі however well correlate with the number of neurons like in the whole brain, so in the cortex of the brain, and also in the brain.
A gallon of soup with mushrooms
The size of the brain of an African elephant was 2.5 kilograms, which meant that it was possible to cut yoga into hundreds of small pieces for processing and processing neurons, so that the conversion of the brain into soup for the specified number of neurons can be made only with pieces of tissue no more than 3-5 grams . I wanted the stars to work systematically, and not like God's soul. Viniclo information about the best suitable tool.
Susana Herkulo-Huzel developed her own method for measuring the number of neurons in nerve tissue: for which brain fragment is given a spleen of the dermatologist, for which the membranes of the clitin are reshaped, but the nuclei are filled with non-thoracic ones. Come out your own "soup". The stability of the pіdrakhunka of the kernels of the new one is taken care of with the help of those who, as if it were good to take care of it, then the kernels will be distributed to the new one step by step. If so, it will be possible to increase the number of nuclei of neurons in 4-5 drops and extrapolate the result for the entire volume. approx. prov. for materialsTED.
We had occasion to victorize a remarkable rіzak in order to take a series of thin zrіzіv for follow-up from the human brain. Razak was handily splitting the kirkov zvivini, but there was one significant shortfall: even a rich speech of the brain was shed on a disk-like knife, which made the appointment of the exact number of clitin at pivkul. As we wanted to recognize the total number of neurons in the brain of an elephant, we needed to cut it by hand on tovstish shmatki, so that we would inevitably spend it to the point of being unimportant.
On one fine morning, I and my daughter (school vacations have just begun) went to the store of the state’s goods with the help of a L-like bracket, which can serve as a stable, flat, regular frame for cutting the brain of an elephant, and also a found knife, which can only be found. lose in one hand.
It was good luck, as a teenager did not miss a moment, even though you could say through the rocks: “Hey, mom, remember, how did they cut the elephant’s brain?”. Having bought everything we needed and safely arrived home, we started to work: for the cob we sawed off the structural reinforcement from the L-shaped bracket, then placed the brain of an elephant. Obviously, these machines cost a hundred thousand dollars, how they robbed the robot of the most perfect rank, but now they stained the pennies, like a pidide and a wonderful manual m'yasnitsky lower?
I laid the pivkul with its flat side on the working surface and spread it between the two supports of the bracket. One of the students leaned on the mist, if I trimmed the pivkul with my left hand and cut it firmly, but carefully. Dekilka roses through us on our hands appeared in full of cuts and ready to cut the brains of an elephant: 16 cuts through the bark pivkulі, vіsіm - through the cerebellum, as well as the cilia moskovy stovbur and the majestic sniff cibulina vagou 20 grams
Pidrakhunok neuroniv. Susana Herculano-Huzel and the students created the brain of an elephant, shown in this photo, to determine the number of neurons, as a way to avenge that similar signs of the human brain.
This was the largest quantity of fabrics, as if they were cut off. One person, processing one fragment a day, spent a lot of time on the analysis of such an obligation, moreover, practically without holidays. It was obvious that a group robot was needed here, moreover, I wanted to take the results for a stretch of six months. But to build a small army of assistants, which is formed by 3 students, the work took more than an hour: two months have passed, and we have harvested less than one tenth of an elephant's brain. Schos treba bulo vigadati.
They gave us the need for the bulk of the internal structures (smooth body, thalamus, hippocampus) for measles, then cut the cerebral cortex into small pieces for trimming, and then split the skin from these pieces into sulfur and white speech. Zagal, we have 381 fragments of fabric, most of them for a vaga bula twice more for 5 grams, and the insoles themselves can be made at a time.
The principles of capitalism appeared more ancient. I spent a few days raising money and showed that I had 2,500 dollars "zayvih" - about one dollar per gram of fabric, which is necessary to obtain. I chose a team and made a proposition for them: you can help a robot if it’s a good one and at the same time take care of a financial wine city. Shvidko formed small partnerships: one student trimmed the fabric, the other spent a prank and insulted each other, shared income. The robot went like a wave of an enchanting wand.
My man, coming to the laboratory, was hostile to the friendly NATO students, who spoke to each other and worked diligently in front of him (it is important that the students celebrated the memorial service, because the laboratory had to milk a little). Gyro Porfirio, having taken upon himself the majestic obligation of robotic preparations with antibodies, and I killed the baby neurons with the help of a microscope, and in six months, we harvested the entire brain of an African elephant - like a plan.
I help…
Listen! The brain of an African elephant has more neurons than the brain of a human. And not just a few more: the mornings are bigger - 257 billion against our 86 billion. Ale - and tse, in a respectful way, "ale" - 98 rows of neurons were planted in the cerebellum, at the back of the cerebellum. In the case of some other savtsya, as we already had a chance to see, the brain also avenged the greater part of the neurons, but in a few cases the show did not exceed 80 hundredths.
Extraordinary distribution of neurons in the brain of an African elephant, leaving a piece of measles in the brain resulting in 5.6 billion neurons. Irrespective of the size of the measles brain of the African elephant, 5.6 billion neurons in them pale in comparison with an average of 16 billion neurons, concentrated in the most modest of the measles of the human brain.
Later, we took away the evidence: no, the human brain does not have more neurons, the lower brain is richer than the volume of the brain of an elephant, but the cortex of the human brain has three more neurons, the lower cortex of the elephant's brain, which outweighs the human brain. It is obvious that the large number of neurons in the brain of an elephant antrochi does not help it in the development of cognitive abilities. This does not give us the right to assert that the number of neurons in the cerebellum is not the dominant factor in the case of the shortness of the brain for thought. .
To come out, the cerebral cortex is left behind. Nature has carried out an experiment, as we demanded, adding a connection between the number of neurons in the cerebral cortex and the number of neurons in the cerebellum. It is possible to explain (and in one piece of explanation) the reverse of the cognitive fluctuations of a human being simply against the great number of neurons in the cortex of the brain.
Although today we don’t have enough data to overcome cognitive deficiencies, which are necessary for matching all kinds of savants, or if we want to be quiet, the number of neurons in the cerebral cortex of which we know, we can also increase the numbers, priming, rereading. Since the absolute number of neurons in the cerebral cortex is the main intermediary factor in the development of cognitive traits, I admit that the classification for this indicator may look like this:
I think it’s more plausible, lower decimal at the same time classifying for the mass of the brain, like a maє, for example, a giraffe, more primates. Whom the clouded ієrarchіya may look like this:
It seems that it is a simple explanation of why the human brain and only wines can at that very hour be so similar to the brain of other species in their evolutionary exchanges, and so breathe in them, giving us the building of a metaphysical journey about our customs of the material.
First, mi - primacy, but tse give us the priority, which belongs to the great number of neurons, "packed" in the small cerebral cortex. And in a different way, the beginnings of technological innovations introduced by our ancestors, we have lost energy exchanges, like other creatures may have a smaller number of neurons in the cerebral cortex nature).
What are the results with us, what do we not have in other creatures? I affirm that the great number of neurons in the cerebral cortex is the most equal to that of today's species. And why should we not kill more human creatures, and what allowed us to pick up neurons in one place?
Let me tell you, it’s more simple: we are preparing our food. Tobto, my zdatnі nadavat our brain is necessary for yogo development of eating, which cannot be said about creatures in the wild. And our brain saves a lot of energy (approximately 25% of the available energy, as we need it). In such a manner, by simplifying the process of tasting the widow and the baby її more balanced and sustenance, the person took on the development of her brain, and the brain, on her back, took on the development of human suspіlstva.

In truth, a person does not grow up with zvivins; In the world of growth, neurons grow and migrate in different zones of the brain, creating furrows and ridges. Until the age of 40, the brain is already very winding, like a grown-up person. Tobto, s navchannya new reliefs do not show up, we just people with them.
However, the world's brain training is actively changing - for the same reason, the plasticity of the brain is changed, but all the same, new zvivini do not appear.

9th place - Human brain - the largest
Proportionately to the whole body, it is possible to achieve a great brain of a person, but the pardon is broadened in the fact that the brain of a person is larger, lower in any other creation.
The brain of a mature person is approximately 1.3 kg and reaches 15 cm of the head. The largest brain is for a sperm whale, the weight should be over 8 kg. Another creature with a great brain - an elephant, your brain becomes close to 5 kg.

As practice has shown, the expansion of the brain does not infuse into the brain. For example, the brain of I.S. Turgenev is important in 2012, and the brain of Anatole France is 1017. The most important brain - 2850 g - manifestations in an individual who suffers from epilepsy and idiocy. Yogo brain in functional wear is not perfect. Henceforth, there is no direct fallow between the mass of the brain and the rosy vibes of the green individual.

It’s true, we can see the very same picture - in people of a frail age, the process of thinking, the memory is fading, in some moods, they are accompanied by senile insanity.
However, it’s not the fault of that, but the way of life, which is the skin of a particular person. Deyaki people kept their thoughts clear until deep old age. Obviously, for whom one meal is not enough - it is necessary to finish the singing mode of work, to eat and drink.

1 month - The myth about 10% of the vicarious part of the brain
Myth, what a strong one, that most people beat up no more than 10% of the brain. Neuroscientist Barry Gordon characterizes the myth as “ridiculously pardoning”, adding: “We can beat all parts of the brain, and the stench can be active.”
Doslіdzhennya pokazuyut, kozhen vіddіl human brain may have its own set of functions. As the myth about 10% is true, then the chance of hurting the brain is much less - we should only care about those, so that a small 10% of our brain was safe. But really, damage to a small area of the brain can lead to serious consequences for our functioning. Scanning the brain also showed that the whole brain has a very high level of activity to get one hour of sleep.
head brain- Center for the management of the whole organism, vouching for thought and knowledge. To be found at the cranial box, as if protecting yoga from the poshkodzhen. It's wonderful, ale wine is fat from the body's organs, so more than half is made up of fat. Tse firmness, in passing, let me think about those who are the most fat, which means the most important. Chi so tse? How important is the human brain? What is the difference in the mass of the brain of a grown-up person, not the old one? How many brains do people have? How much to differ in which people and women? Chi pours intellect into the brain? What is the average mass of gray speech among representatives of different nationalities? Who has the largest and smallest brain in the creaturely world? Let's try to find out the answers to all power supplies.
Vaga brain and factor, yakі on the new inject
The human brain, like the whole organism in a flash, is changed by the stretch of a mustache life. The head brain of a person begins its development from 15 to 21 days of intrauterine development of a child, at the time of birth it is fully formed and it becomes 300 to 500 grams. For the first 27 years of life, the head of the brain increases in proportion to the growth of the whole organism, and then changes by approximately 3 grams per river. Archimedes, at the hour of his rebuking, tried to virahuvati, how to take care of the brain of a grown man by placing his head in a barrel of water. Then, when the water was blown, it splashed, and on the substantiation of the number, the mass was counted. The result of such an elaboration is, apparently, not very accurate and understandable only to Archimedes himself. On this day, it has been established that the average weight of the human brain should be 2% of the total mass of the body, in general, it should be 1 to 2 kg.
Korisno recognize: Why is the development of the brain important for a modern person and how to be effective
In the body of a human head cream, which is found in the cranial box, there are 2 types:
- spinal. Roztashovuetsya in the cervical, thoracic, transverse and krizhovy vіddіlі ridge. Yogo middle vaga stores a total of 30 - 50 g, dozhina is about 50 centimeters;
- brush. Roztashovuetsya in the tissues of the stegon, ribs, pelvis and sternum. Important 2000-4000
The mass of the brain of a man is not richer than that of a woman, in total by 100 - 150 g, to that, due to the nature of a woman, a woman is smaller than a man. And if you virahuvati vodsotkove spіvvіdnoshennia, then the vaga of sіroї speech among women will be greater. The largest woman's "reason" is important in 1565, the smallest - in 1096. In 1956, a 10-year-old girl successfully passed an IQ test, with a result of 228. It’s not worth talking about the safety of a person’s reconciliation in that since there are more stench for a woman’s growth, that means smarter. Turgenev, for example, having taken into account that one skull is worth close to three kilograms.
Chi pours intellect into the brain? The ingenious mathematician Gaus, having become 2400, the writer Byron had more than 2000, Lenin only 1340. Іsnuyut ailments, so like Alzheimer's ailments, which infuse cerebral measles into the society, thereby increasing the volume, but not giving up the mind. Schizophrenia and parts of depression are just as bad. The largest mass of the brain was fixed in a rose-colored person - around 3000. And as we believe it, instead of the cranial box of Australopithecus, it was about 500g. With great respect for numbers, you can grow visnovoks, so that the mass of the brain of a healthy person does not spit on roses. Rivne to intellect and talent to lie in the quantity of sounds, in the quantity and density of rotting as a form of electrical impulses of neurons. Neurons analyze the information to come, react to incoming calls, control the activity of the entire organism as a whole. The stench is the very same speech.
Korisno recognize: Is it true that epilepsy is transmitted from depressions
It has been brought to light that the mass of the brain is due to nationality and racial affiliation. Anthropologists are convinced that there was a person who had a person who turned black shchira. Byelorussians - 1429, the lightest among the Australians - 1185 and the French - 1300. Among the Japanese and Koreans, who seem to have a tendentious status, the sir speech in the obyas is no more than 1400.
From what was written, it became clear that a lot of factors are added to the heaviness of the human brain. So it is with the creatures. A lot of great savtsiv scho is impossible to boast of the great mass of the brain. For example, prehistoric dinosaurs.
