Drafting a ‘dysfunctome’: Faulty connections to subthalamic nucleus characterize disparate brain disorders
Different circuits between the millimeters-wide structure and the cortex go awry in Tourette syndrome, obsessive-compulsive disorder, dystonia and Parkinson’s disease, a new study of human brain scans suggests.
