Big brains don't mean smarter

Many people believe that the brains of the developed peoples have a larger mass. This is incorrect. Because the British brain weighs an average of nearly 1,350 g, less than 130 g compared to a less developed nation than Buriat.

The natural scientists of all time have speculated that the brains of genius and ordinary people are not the same, but it is unclear at what point? The intense search began 7,000 years ago and continues. And in that time mankind has learned many interesting things about himself.

Residents of different continents are ' equipped ' for different brain weights. European Race: 1,740 g, Mongoloit race (temporarily called yellow skin) 1,330 g, Negro (black) race 1,240 g and Southern Mongolian race 1,190 g.

Why is there such a difference? The most common explanation is: The brains of the developed peoples are more massive. It makes sense, but not exactly, because it will be difficult to explain the average British brain weighs 1,350 g, and the Buriat brain - less developed - weighs 1,480 g. The French brain is also lighter than the Keri, which lost to France in terms of development.

Picture 1 of Big brains don't mean smarter The Russians, too, at the time of the empire, when Russia outperformed the surrounding peoples, their brains were still lighter than many minorities like Baski, Belan, Chesnya .

However, a nation only needs to eat better for a while, be happier and have more intelligence, the brain changes immediately, its capacity increases. For example, the volume of the skull of the French lived 100 years ago more than 36 cm 3 compared to their predecessors in the 18th century. This phenomenon was also discovered in Egypt: In the flourishing period of ancient culture, brain volume is greater than 45 cm 3 compared to long periods of recession. In the late 20th century, the average weight of Japanese brains increased by 30 g in men and 15 g in women.

There are those who think that human biological evolution has stopped, only the evolution of man-made technological evolution remains. At some point, this technique will be stronger than humans and destroy people. Not really. Anthropologists say that in the last 100 years, the human brain has weighed more than 40 g.

Can evolution turn us into an oversized big creature? The head cannot be bigger than the body. At a certain stage, nature, when fully exploiting its capacity to develop, will probably focus on improving the brain of substance. According to scientists, by this method, nature is ' training ' current geniuses and talents.

What's different in the brain of genius?

The Russian writer Ivan Turgenev's brain is twice as big as the French writer Anatole France. Could Turgenev be twice as smart? Hat size cannot be a measure of human intellectual capacity - that was clarified 120 years ago. At that time, the German scientist T. Bishof made a scientific feat: He studied the gray matter mass of 2,000 people representing different social classes who had farewell this world. People with the heaviest brains are not scholars or aristocrats but boatmen. The next generation of research has established that the brains of different people are not the same as trees in the forest.

The Russian morphologist, Professor Vaim Avorykin, recently proposed a hypothesis: Small brain regions change more than the medium and large brain regions . That means that the genius of the genius is predominantly due to the combination of small transformations . Even the least variable area of ​​the human brain - slit Sylvius - also has four relatively stable variants.

Another important factor: The excess of gray matter in some areas is compensated for the shortage in some other areas. Scientists at the Brain Research Institute in Germany recently said that in a musician with a delicate hearing, the fourth grade in the newborn auditory shell is twice as thick as a non-musician; In painters, the fourth grade in the primitive visual shell is also thicker. That is probably what created the facilities for genius.

Recently, Professor Sergei Savelev, Head of the Laboratory of the Human Morphology Institute under the Russian Academy of Sciences, carried out the intention of V. Avorykin: Modeling the artist's brain. The artist needs visual stimulation, sharp eyes, visual memory, rich imagination, steady hands. In order for all these to arise and work, there must be a combination of 26-28 factors. The ability of these elements to appear at the same time is very small, so the genius is always rare.
