Scientists have found a correlation between parts of the brain related to social perception and a person’s number of Facebook friends. The study is part of a set of studies examining how the brain and Internet interact. In a study involving 125 British university students who were subjected to an MRI brain scan, the ones with more Facebook friends showed that they have a higher volume of brain matter in the amygdala, the right superior temporal sulcus, the left middle temporal gyrus and the right entorhinal cortex. The amygdala is associated with emotion, while the other regions tend to be associated with interpreting body language and social perception. The British scientists, writing in a study published Wednesday in the journal Proceedings of the Royal Society B, cautioned that Facebook does not necessarily make parts of the brain bigger.
