Bilateral subthalamic stimulation
What this trial is about
This program aims to understand the role of the subthalamic nucleus in the control of the movement in healthy humans and patients with Parkinson's disease, how the STN dysfunction contributes to akinesia and how the STN stimulation improves motor signs in PD patients .
