Dynamic Motor Cortical Responses to Subdural Electrical Stimulation.

Medical University of South Carolina

Overview

The purpose of this study is to better understand how subdural electrical stimulation of the brain affects motor cortical oscillations

Direct cortical stimulation (DCS) has shown the potential to improve symptoms in patients with Parkinson's disease, however its effects have not been consistent in randomized studies to date, limiting widespread adoption of this technology. A critical gap in our knowledge is a detailed understanding of how DCS affects motor areas in the brain. Investigators propose using subdural DCS (sDCS) while simultaneously recording directly from motor cortex using subdural electrocorticography (sECoG) in patients undergoing deep brain stimulation surgery. Investigators expect this novel approach to broaden our understanding of sDCS application and possibly lead to therapeutic advances in this population.
