Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to learn more about the brain activity underlying Parkinson's disease cognitive impairment. The investigators will utilize neural recordings from corticostriatal structures performed during deep brain stimulation surgery to measure neural activity underlying nonmotor symptoms of Parkinson's disease.
