Neurofeedback of Activity in the Supplementary Motor Area for Tourette Syndrome

The aim of this study is to train patients with tic disorders to control activity in a region of their brain that has been associated with the urge to tic. Patients will be given direct feedback regarding activity in this brain area while they are undergoing functional magnetic resonance imaging (fMRI) scanning, and will try to learn to control activity in the region during these feedback sessions. In separate sessions, patients will be given sham feedback based on the brain patterns of a prior subject rather than their own brain patterns. Our primary hypothesis is that the biofeedback training will reduce their tic symptoms more than the sham feedback.
