Abstract

Abstract

En 中文
Deep brain stimulation (DBS) of the globus pallidus internus (GPi) can reduce levodopa-induced dyskinesias, yet GPi targeting sometimes fails or worsens them, suggesting distinct prokinetic/antikinetic circuit mechanisms. Using the broad GP sampling from the CSP-468 trial, we sought to identify stimulation zones and connectivity maps that predict dyskinesia outcomes in GPi-DBS patients.
