Dr. Butler is a neuroscientist and physical therapist with a special interest in motor control, neuro-rehabilitation, functional neuroimaging, and transcranial magnetic stimulation. He is the co-director of TMS laboratory within the Center for Rehabilitation medicine. He is the Emory co-PI of the Functional Imaging in Constraint Induced Therapy (FICIT) study (R01 HD40984, George Wittenberg M.D.Ph.D, Wake Forest, PI) which evaluates the effect of constraint-induced movement therapy on cortical reorganization following stroke using TMS and fMRI co-registration among EXCITE participants.
Dr. Butler is currently the PI of a project investigating the use of mental imagery to improve motor deficits in patients with stroke National Center for Complementary and Alternative Medicine (NCCAM 5R21AT002138-02)
