Deep Brain Stimulation (DBS) Study for Parkinson's Disease This study explores how certain cues can help people with Parkinson's disease move more easily. Parkinson's disease is a disorder that affects movement, causing symptoms like tremors, stiffness, and slow movement. During surgeries called deep brain stimulation (DBS), doctors place small devices in the brain to help control these symptoms. In this study, 40 participants with Parkinson's will perform simple movement tasks while awake during their DBS surgery. This helps researchers understand which parts of the brain help improve movement. Participants will have two temporary electrode strips placed on their brain for research purposes. These recordings may help create better treatments for symptoms that current medicines can't fix, like freezing of gait (when a person temporarily feels like their feet are stuck to the ground).

• No extra visits required; all procedures happen during the DBS surgery.
• Participants must be able to cooperate during the 40-minute procedure.
• Study has specific inclusion and exclusion criteria for participation.
