Eligibility: Participants must be between 30 and 75 years old, have had Parkinson's Disease for 4 to 20 years, and meet specific health criteria. They cannot have certain other medical conditions or be in other clinical trials recently.
- Participants will need to attend several doctor visits and have tests like MRI scans.
- They must agree not to have other brain surgeries or join other studies during and after this trial.
- After the surgery, participants should use birth control as per local rules for a year.
