Scientists Link Brain Structure To Social Media

Ever wonder how our brains have evolved in the age of Facebook, Twitter and hundreds of “friends”?

A team of researchers has found a link between the size of our amygdala, the epicenter of our emotions, and the size and complexity of our social networks. The bigger the amygdala, the bigger and more complex the network.

In a study published yesterday in Nature, doctors from Boston University and Harvard University measured the social networks of 58 adults based on two factors: the number of people they were in regular contact with (size), and the number of social groups these contacts could be divided into (complexity). They also measured the volume of the participants’ amygdalas and hippocampus, as a control.
