Research on how a larger amygdala region in the brain may make it easier for some people to maintain a large social network.
People with large, highly complex social networks tend to have larger amygdala regions than those with fewer friends, according to a study published in Nature Neuroscience.
It’s the first study to demonstrate a link between amygdala volume and social network characteristics within a single species.
They found that the gregarious types, those who reported having regular contact with comparatively large numbers of people from a variety of social groups, tend to have larger amygdala volumes.
