Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This study involves patients who are already planning to have deep brain stimulation (DBS) surgery to treat the symptoms of severe Parkinson's Disease (PD). The study has two goals: 1. to evaluate the effectiveness of implanting DBS electrodes in the two most common locations for DBS (subthalamic nucleus (STN), and globus pallidus interna (GPi)), instead of just one electrode, on each side of the brain; and 2. to develop an adaptive DBS system using brain signals measured from these two electrodes.
