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. （点击BBC网站查看原文）

社交网站可能改变大脑

       据英国广播公司报道，一项最新研究显示，社交网站可能会改变人的大脑结构及社交生活。

       脑部扫描显示，一个人在脸谱网上拥有的朋友与他大脑某部位的大小成正比。

       研究人员称，目前尚不清楚是社交网站促进了脑部物质的生长，还是脑部结构决定了他们是否擅长社交。

       另外，一个人脸谱网上的朋友人数与他现实中的朋友人数也成正比。
