The structure of the brain depends on the communication

You have a lot of time to spend with friends? This could mean that one part of your brain more than usual.

Of the brain called the amygdala, located deep inside. Brain 58 volunteers preliminary study has been scanned. Found that those who socialize more with friends and family, the amygdala was larger than the others.

This can be explained by the fact that this particular brain region is responsible for communication. For example, helps to define or identify familiar faces of friends and enemies.

However, until the investigation was unable to answer the question, what of it - enlarged tonsils or communication - is the cause but the consequence. The study's author Lisa Feldman Barrett said that, most likely, little bit of everything.

The study is published in the journal Nature Neuroscience.
