Abstract Elevated subthalamic (STN) beta (12–32 Hz) local field potentials (LFP) are a hallmark of Parkinson’s disease and closely tied to synchronized spiking. The biomarker guides deep brain stimulation (DBS) lead implantation and is under investigation to inform DBS programming and adaptive DBS, yet its prevalence has not been independently assessed. This study assesses the biomarkers prevalence and investigating its relationship to synchronized beta-bursting neurons.
