When I see an attractive face, it grabs my attention. It's because a region deep in my brain, called the midbrain, puts out reward signals.
For the first time, scientists have electrically stimulated people's midbrain region without using invasive electrodes. When they stimulated the region, people tended to judge faces as more attractive than they normally would.
The study has a serious side. Stimulating the midbrain could help treat Parkinson's disease and depression. I agree with the scientists when they say that's much more important than playing Cupid.
