It’s pretty much undeniable that the Internet is changing the way we think and do things. But could it go so far as to actually rewire our brains? Well, in 2011, a study came out suggesting it might be doing exactly that.By scanning the brains of 125 students in London, researchers noticed a direct link between the number of Facebook friends the students had and the amount of grey matter in certain regions of their brains. Since these regions are thought to play a part in memory, social interaction, and possibly even autism, this is kinda important. Now, the study can’t tell us for certain whether social media is causing this rewiring or whether people with these different brain structures are simply more likely to flock to Facebook. But there is plenty of evidence that the Internet is affecting the way we behave, so who knows what else it might be doing.
