The study's aim is to better understand motivation and value-based decision making in Parkinson's patients through neurophysiology using Medtronic's Percept PC DBS device.
The investigators will ask patients to complete reward-based decision making tasks in clinic and at home in the presence and absence of Percept PC deep brain stimulation and medication. The Percept PC device has the ability to stream data during paradigms and chronically at home. Patients at home will also be fitted with a wearable device which records motion, sleep, heart rate variability, and self-reported metrics. The investigators will use spectral techniques and statistical analysis to identify the relationship between brain signals and motivation.
