Study Summary

Patients with Parkinson's Disease who undergo Deep Brain Stimulation surgery receive symptom relief due to electrical stimulation of the brain. The target for the stimulation, in many cases, is the subthalamic nucleus (STN). The brain area just above the STN is called the rostral Zona Incerta (rZI). The rZI may be a potential target for deep brain stimulation, in combination with the STN.
