Imaging Study for Parkinson's Disease DBS

This study is looking at how a specific type of deep brain stimulation (DBS) affects the brain in people with Parkinson's disease. Researchers will use bipolar DBS stimulation through contacts 3 and 2 of the Medtronic Percept/Percept RC DBS System. The goal is to see how this stimulation changes the blood oxygen-level dependent (BOLD) signal in the leg region of the primary motor cortex, which is a part of your brain that controls movement. This change will be measured 8 hours after stimulation. You may be able to join if you are 21 or older, have Parkinson's disease, have an MR-compatible DBS device (Medtronic Percept/Percept RC DBS System), and can speak English. The study aims to enroll 20 participants.

  • Change in Blood Oxygen-Level Dependent (BOLD) signal in leg region of primary motor cortex8 hours

    Data will be obtained from functional MRI scanning with the participant at rest, with DBS cycling between ON and OFF stimulation. The change in BOLD signal in the leg region of the primary motor cortex will be obtained by contrasting signals obtained during ON vs. OFF stimulation states. The change in BOLD signal represents the increase/decrease in brain activity in the leg region related to stimulation.
