Coordinated reset deep brain stimulation (CR DBS), a promising treatment for Parkinson's disease (PD), is hypothesized to desynchronize neuronal populations. However, little in vivo data probes this hypothesis. In a parkinsonian nonhuman primate, we found that subthalamic CR DBS suppressed subthalamic and cortical-subthalamic coherences in the beta band, correlating with motor improvements. Our results support the desynchronizing mechanism of CR DBS and propose potential biomarkers for closed-loop CR DBS.
