The brain of someone in love looks similar to the brain of someone on cocaine. After scanning the brains of individuals in love versus those that aren't in love, scientists have discovered that there is a vast difference in the brain activity of each individual. Those from the 'in love' category showed increased activity in several areas of the brain, including the parts of the brain that deal with reward, motivation, emotion and regulation, as well as in the social cognition network. While love has been the subject of poems and songs since the beginning of time, it wasn't until relatively recently that it was the subject of neurological research. Today, scientists continue to dig in to see what being lovesick is really doing to our brains!
