Parkinson's Disease (PD) affects how the brain controls movement. One problem in PD is that the brain's "gamma oscillations" (brain waves important for movement and learning) are not working well. Transcranial Alternating Current Stimulation (tACS) is a safe method that sends small electrical currents to the brain, aiming to fix these brain waves. This study explores if tACS can help improve movement and learning in PD patients.

Participants will receive gamma-tACS on a part of the brain called the primary motor cortex (M1), which is involved in controlling movement. Researchers will use special techniques to measure if patients' movement skills get better.

• Study Duration: Information on how long the study lasts is not provided.
• Eligibility: Participants must have a PD diagnosis but no severe mental health issues or other brain disorders.
• Risks: Participants with certain conditions or on specific medications that affect the brain might not be eligible.

This study is important because it might find a new way to help people with PD improve their movement skills through brain stimulation.
