Brief Summary

Patients with Parkinson's Disease will be studied before, during, and after a deep brain stimulation implantation procedure to see if the stimulation location and the size of the electrical field produced by subthalamic nucleus (STN) DBS determine the degree to which DBS engages circuits that involve prefrontal cortex executive functions, and therefore have a direct impact on the patient's ability to inhibit actions.
