About this trial
The purpose of this project is to increase our understanding of the early state and temporal evolution of neuroplastic changes in the cortex and subthalamic nucleus (STN) of people with PD, and the relationship of these changes to the emergence and expression of PD motor and non-motor signs. Neurophysiological biomarkers derived from this work may be important for the early detection and prediction of progression of disease. They can also provide the means to assess the efficacy of interventions designed to prevent or slow disease progression.
