Researchers are exploring for brain signals that mark when someone is experiencing OCD symptoms in order to shape future brain stimulation treatments.

Undergraduate engineers have created a prototype glove that senses when someone with trichotillomania reaches to pull out hair.

Researchers report that repeated noninvasive, pain-free brain stimulation curbed behaviors common to obsessive-compulsive disorder.

Brains scans of people who have obsessive-compulsive disorder reveal that "different brains respond to different treatments."

A brain circuit that underlies repetitive behavior in roundworms could shed light on Tourette's and autism in humans.

Research with mice shows how sensory and motor signals have different paths and effects on our behavior, which could lead to Parkinson's treatments.

"This is not some deep dark problem of behavior—OCD is a medical problem, and not anyone's fault. With brain imaging we can study it just like heart specialists study EKGs..."
