Elevated beta (β; 13-30 Hz) synchronization within the subthalamic nucleus (STN) characterizes bradykinesia in Parkinson's disease (PD). β oscillations may serve as biomarkers for off-period motor symptoms and control signals for adaptive, closed-loop deep brain stimulation (DBS) in PD. However, their relation to striatal dopaminergic denervation and PD progression remains uncertain.
