Patients who have been randomized into Group 1 will undergo DBS implantation while awake. On the morning of surgery, the patient will undergo placement of the stereotactic head frame under local anesthesia. A CT scan will be performed for stereotactic planning, which will be fused to a preoperatively obtained MRI. The coordinates for the planned target will be selected using standard coordinates based on known relationships with the anterior commissure - posterior commissure plane, along with anatomical structures visualized on the MRI scan.
