Growing a Bigger Brain with a Larger Social Network
But is having a bigger amygdala better? One research team's speculation:
"In the context of our findings, Striedter’s “large equals well-connected” rule suggests that humans with a larger amygdala with denser connectivity might be better equipped to seek out, learn about, and coordinate appropriate neural and behavioral responses to multifaceted visual information that allows people to develop and maintain a larger, more complex social network."
To calculate your social network, fill out the Social Network Index here. If you want to figure this out using your Facebook statistics, check here. The SNI reflects "how many people you see or talk to on a regular basis including family, friends, workmates, neighbors, etc."
