More Facebook Friends, More Gray Matter in Brain? - Yahoo! News

Future job interviews may routinely feature neuroimaging (or perhaps scans will be an expected part of your résumé/LinkedIn profile/etc.)

The researchers found that the number of Facebook friends that students had correlated with the size of the gray matter in several areas of the brain.

One of the areas, the amygdala, is associated with memory and emotional responses. An earlier study found that this area was larger in people who had many real-world friends. Now it has been found that that's also true for those with lots of online friends, Rees said.

In addition, three other areas of the brain -- the right superior temporal sulcus, the left middle temporal gyrus and the right entorhinal cortex -- were also larger among those with lots of Facebook friends, but the size of these areas did not correlate with the number of real-world friends, the researchers noted.
