UNITED STATES, WASHINGTON (VOP TODAY NEWS) — Scientists from the Ruhr University in Bochum and the Humboldt University of Berlin now know what is going on in the brains of Alexander Druz and Anatoly Wasserman, as well as other scholars who “know everything.”
A special type of MRI, the so-called diffusion-tensor MRI, helped researchers look into the brain of the “experts”.
To study the characteristics of the brain of scholars, 324 people were invited with varying degrees of knowledge on general issues (information that is relevant in various kinds of quizzes).
The subjects were asked more than 300 questions affecting various fields: art, architecture, science, history and more. At the same time, with the help of diffusion MRI, specialists tracked the connections between different areas of the brain.
The results showed that the participants who demonstrated the greatest amount of knowledge on all issues had much more effective brain connections – they had the most durable and shortest connections between neurons. But the number of neurons with the level of erudition did not correlate in any way.
“It’s natural that people with more extensive knowledge have better brain connections,” says lead author of the study Erhan Genk, research fellow at the Department of Biopsychology, Ruhr University in Bochum.
According to Genk, various pieces of knowledge are stored at different points in the brain. Imagine you are being asked a simple question: in what year did the man land on the moon? We store the “Moon” in one brain zone, the “moon landing” in another, and, in fact, the year when the event occurred, in the third.
Thus, when answering the question, the brain must connect the “Moon” with the “landing” and “year”, and he does this through neural chains. It is logical that with more effective connections, the right information comes to mind quickly and easily. Otherwise, begins “uh … well … how is it … forgot.”
Another thing is that it is not entirely clear why, nevertheless, some people have more effective brain connections compared to others. Perhaps someone is born with a special brain architecture, or perhaps brain connections are developed during training (for example, with regular participation in quizzes).
To understand this, scientists will have to track changes in the brain of the subjects for several years, which, in fact, they are going to do in the future.
