EEG and DBS in PD

We will look at the effect of deep brain stimulation (DBS) in Parkinson's Disease (PD) on cortical activity during movement termination. Using scalp EEG from PD patients treated with DBS either at the subthalamic nucleus (STN) or the globus pallidus internus (GPi) and aged-matched healthy control participants while performing our novel continuous movement task, we will measure average power changes time locked to plan/unplan stop conditions across sensorimotor cortices and midfrontal cortex.
