BBC’s morning program, “BBC Breakfast,” had a 5-minute segment about deep brain stimulation , or DBS. DBS involves the use of electrodes which are implanted into the brain through holes drilled in the skull. The electrodes are attached to a battery pack which delivers small amounts of electricity to stimulate or inhibit specific areas in the brain. Around the world, more than 40,000 people have gone through this procedure. Deep brain stimulation has produced promising results in the treatment of diseases such as Parkinson’s disease, depression, obsessive-compulsive disorder, and dystonia.
