Deep brain stimulation (DBS), in which implanted electrodes deliver electric jolts to the brain, has shown great promise in treating neurological disorders: it is already approved to treat Parkinson's disease and is being tested to treat severe depression, obsessive-compulsive disorder, traumatic brain injury, and other ailments.
