A study links number of Facebook Friends to a structure in Human Brain

On stumbling upon this recent research, I think anyone who wants to use social networks to sell products, should first get a Brain MRI scan done; as he/she will know on the very first day of his/her social media marketer journey; whether he will be able to friend 3000 Facebook users and then sell products to them.

According to a recent research, there’s a Facebook-like feature in our brains that rules our social network, and the structure is easily visible in a Brain MRI scan.

The research found that, Amygdala, a small almond- shaped structure, deep in the temporal lobe governs the number of friends one is likely to make -- the larger the amygdala, the wider and more complex is its owner's network of pals.

For the study, the researchers asked volunteers aged between 19 to 83 to complete questionnaires which measured how many regular social contacts they had and in how many groups.

Magnetic resonance imaging scans of these participants found a positive link between big amygdalas and the richest social lives. In short the bigger the size of amygdala more are the number of friends and more is the tendency to make large groups and meet new people.

The evolutionary story of amygdala:

According to the lead researcher Professor Lisa Barrett, a psychologist at Northeastern University in Boston , Massachusetts, the findings of the research were consistent with "social brain" theory, which suggests that human amygdala evolved to deal with an increasingly complex social world. Additional studies in this area have shown that primates living in larger groups tend to have larger amygdalas. --------
