Does Facebook Make Your Brain Bigger?

Maybe. Parts of your brain, anyhow. According to new research, those who are most active in social media have larger brain parts than others (even when compared to those who are social in real life):

How social you are on social networks may depend on the size of your brain, according to new research. Or, at least, the size of your superior temporal sulcus, middle temporal gyrus, entorhinal cortex and amygdalae.
The research, from University College in London, discovered that those who are more social in general tend to have larger amygdalae than their peers, but that those who are more social online also have increased sizes of the right superior temporal sulcus, the left middle temporal gyrus and the right entorhinal cortex. For those curious: The superior temporal sulcus is known to give cues about others' emotions, while the middle temporal gyrus helps us react to said social cues. The entorhinal cortex, meanwhile, has been linked to our memory.
Researchers are uncertain what this information means or, more interestingly, whether the larger brain sections are the cause or the result of the size of the subjects' social networks.
