This study is investigating how brain networks control movement in people with Parkinson's disease (PD) and essential tremor (ET). Researchers believe that these conditions involve abnormalities in these brain networks. The study will look at how two treatments, Apomorphine Injectable Solution and Subcortical Stimulation (a type of deep brain stimulation), affect these networks. The goal is to better understand how these treatments work and how they relate to symptoms and movement. You may be able to join if you are 18-89 years old, have Parkinson's disease and are recommended for deep brain stimulation, and can cooperate during a conscious surgical procedure. The study plans to enroll 120 participants, but its current status is unclear.

Study design

This is an interventional study planning to enroll 120 participants. It will involve applying Apomorphine Injectable Solution and Subcortical Stimulation.

What's involved

You would need to undergo a conscious operative procedure for up to 40 minutes. Cortical ECoG and subcortical recordings, along with behavioral assessments, will be measured at baseline.

Compensation

Not stated in the trial record.
