The structure of the human brain depends on the number of friends

The relationship between levels of social interaction of humans with the development of its nervous system has interested scientists for a long time. It is known that the number of sick social relationships generally has a positive effect on public speaking skills, and ability to support conversation and communication skills. A group of scientists from Oxford University have conducted a study, which found that the number of friends is able to change the structure of the human brain.

For the research was gathered a group of volunteers. They were asked during the month to celebrate all of the encounter that took place during this period of time. Also take into account phone calls, short message, SMS, and instant messengers, e-mails. Scientists have found that there is a definite link between the number of social ties and mental faculties of man.

Data were installed after brain scans of subjects. People with a large number of friends and acquaintances, had a special building structures of the cerebral cortex. In particular, they had better-developed region of the anterior lumbar crust. This area is responsible for understanding between people. The high activity of the lumbar bark helps to establish communication and easier to find common ground with a stranger.

In addition, sociability developed neural connections in the brain. This allowed the signal to reach faster to the desired patterns. Additional links help a person in structuring and sorting information, planning and delineating the essence of the overall information flow.

It should be noted that this development the brain is not always associated with a General increase its volume and activity. In some cases, specific areas may be less active in them will be at a reduced level.

There is another interesting fact associated with the social life of man. The average number of friends is from 20 to 40 people. However, some had regular contact only with ten friends.
