Want People To Look Hotter? Get Your Brain Zapped

To the list of curious things getting your brain zapped can do, add this: make the people around you seem more attractive.

Researchers from the California Institute of Technology recently studied that effect by giving 99 study participants 15 minutes of transcranial direct current stimulation, or TDCS, an electrode-based, non-invasive way of juicing the brain. (A company is also marketing TDCS as a very sketchy means of getting better at video games.) The participants got an fMRI scan before and after the brain shock, and were shown faces while in the fMRI machine. After the zapping, the participants rated the faces as more attractive. The fMRI, meanwhile, showed increases in activity in the patients’ prefrontal area and midbrain, as well as a higher output of dopamine.

The midbrain is a source of dopamine, a neurotransmitter associated with rating of attractiveness, as well as a long list of neurological disorders. So this study was a proof of concept: TDCS can be used as a non-invasive way of activating the midbrain, up to the point of influencing behavior. The findings could have implications for people suffering from neurological disorders schizophrenia, depression, and Parkinson’s.

Maybe it can help you be nicer to your co-workers, too.
