A new research suggests that social network sites may alter people's minds as well as their social lives, BBC reported.

Brain scans show a direct link between the number of Facebook friends a person has and the size of certain parts of their brain.

It's not clear whether using social networks boosts grey matter or if those with certain brain structures are good at making friends, say researchers.

It also showed that the number of Facebook friends a person has reflected their number of friends in the real world. （點擊BBC網站查看原文）
