Love Hurts and it is real

"Researchers recruited 40 volunteers who had experienced an “unwanted romantic breakup” in the past six months. They were asked to bring a photo of their ex and a photo of a same-gendered good friend to a brain-imaging lab.

Inside a functional magnetic resonance imaging (fMRI) machine, the participants were shown images of their former partner and asked to recall the breakup. Then they were shown images of their friend. They were also subjected to physical pain (a hot stimulus on their left forearm).

Just the fact that you are doing something for yourself and engaging in something that gives you hope may have an impact."

- Tor Wager

As these stimuli were alternately repeated, the subjects rated how they felt on a scale of 1 (very bad) to 5 (very good). Meanwhile, the fMRI machine tracked their brain activity.

While not identical, the regions that lit up during physical and emotional pain were similar.

This finding alone sends an important message to the heartbroken, said senior author Tor Wager, a professor of psychology and neuroscience at CU Boulder: “Know that your pain is real – neurochemically real.”
