Researchers, Using Light to Activate Neurons, Make Mice Obsessive-, or Not

Mind-control optogenetics experiments in mice give new clarity to the neural circuitry that underlines repetitive behaviors.

Two teams of researchers have pinpointed some of the neural circuitry that underlies compulsive grooming behaviors. The discoveries, reported in Science on Thursday, could guide new treatments for people with obsessive-compulsive disorder, autism, and other conditions that exhibit symptoms of repetitive and compulsive actions.
