Who can join

Ages 40 and older · All sexes

Inclusion Criteria:

* Scheduled to undergo deep brain stimulation surgery under local anesthesia at Vanderbilt University Medical Center
* Planned clinical electrode trajectory that contacts caudate
* Age greater than or equal to 40

About the study

The goal of this study is to learn more about the brain activity underlying Parkinson's disease risk taking and reward seeking behaviors. 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.
