The same circuit that controls your jonesin’ for just one more is also, the American Physiological Society says, in charge of your heartbreak:
The pain and anguish of rejection by a romantic partner may be the result of activity in parts of the brain associated with motivation, reward and addiction cravings, according to a study published in the July issue of the Journal of Neurophysiology (http://jn.physiology.org/).
The study’s findings could have implications for understanding why feelings related to romantic rejection can be hard to control, and may provide insight into extreme behaviors associated with rejection, such as stalking, homicide and suicide—behaviors that occur across many cultures throughout the world.
…
In the study, researchers used functional magnetic resonance imaging (fMRI) to record brain activity in 15 college-age, heterosexual men and women who had recently been rejected by their partners but reported that they were still intensely “in love.” The average length of time since the initial rejection and the participants’ enrollment in the study was 63 days, and all participants scored high on a psychological test called the Passionate Love Scale, which determines the intensity of romantic feelings. All participants said they spent more than 85% of their waking hours thinking of the person who rejected them, they yearned for the person to return and they wanted to get back together.
