After scanning the brains of 100 students from Southwest University in China, researchers discovered differences in brain activity between those who were in love, those who weren't in love and had never be in love, and those who had recently broken up with someone they loved (called what the researchers called "ended love"). Participants in the study were told to think of "nothing" during the scans, enabling the scientists to get a better idea of their everyday brain activity. As The Telegraph explained, " Those from the 'in love' category showed increased activity in several areas of the brain, including in parts that deal with reward, motivation, and emotion regulation, as well as in the social cognition network. The amount of activity in some parts positively correlated with the duration of love for the in love group. For the 'ended love' group, the longer they had been out of love, the lower the amount of activity detected in these areas of the brain."
We all know that falling in love messes with your head. But what does it actually do to your brain? A lot. A 2015 study provided the "first empirical evidence of love-related alterations in brain functional architecture."
