an entertaining study of Chinese neuroscientists. Scientists
interested in the question of the difference in brain activity between
children born only in the family, and children having
siblings. It turned out that the former have distinctive

people to pass a series of test tasks to assess their intellectual
abilities, creative thinking and determination of personality traits.
In addition, MRI diagnostics of brain structures was performed.
According to the results of the experiment, neuroscientists learned that
the intellectual sphere of the subjects is not much different. However in
other there are certain differences:
- The volume of gray matter of the supra-edge gyrus (part of the parietal lobe,
in which speech perception and analysis takes place) in single children was
more than the second group. This explains their greater flexibility.
- The mass of gray matter of the prefrontal cortex responsible for
generation and analysis of emotions was less in children born
the only ones in the family. This fact indicates that such
guys are less peaceful and benevolent towards

The experiment covered only one region and only young

results for large populations. But still this is the first step in
unraveling the features of the work of such a complex body as the head
brain. It is already obvious that the anatomical structure of the brain structures
interconnected with the behavior and character of a person.
