Amygdala volume and social network size in humans
We found that amygdala volume correlates with the size and complexity of social networks in adult humans. An exploratory analysis of subcortical structures did not find strong evidence for similar relationships with any other structure, but there were associations between social network variables and cortical thickness in three cortical areas, two of them with amygdala connectivity. These findings indicate that the amygdala is important in social behavior.
Well here is an interesting one. Do they try to conect to more people because they are afraid or conservative or is there a different function of the amygdala that we have missed in the orchestra of the mind's structures.

PResumably this is a pre-cursor to sub-cultural groups is it also a precursor to personality?
