Parkinsonism-Related Oscillations in the Cortico-Basal Ganglia-Thalamic Network During Movement: Beyond the Frequency Range

This study records brain and movement signals in patients with Parkinson's disease who have a deep brain stimulation (DBS) device implanted in an area called the subthalamic nucleus (STN). Researchers want to understand the abnormal brain wave patterns (oscillations) that cause movement difficulties and how they change during activity. **You may be eligible if...** - You are between 18 and 75 years old with idiopathic (standard, non-genetic) Parkinson's disease - You have recently received a PERCEPT™ deep brain stimulation device (within the last year) or you are scheduled to receive one - You are able to perform a simple motor task - You have health insurance coverage - You are able to provide written informed consent **You may NOT be eligible if...** - You are unable to give consent personally - You are under legal guardianship or court-ordered protection - You are pregnant or breastfeeding - You have a serious uncontrolled physical or psychiatric illness Talk to your doctor to see if this trial is right for you.
