The physiological effect of lesioning or deep brain stimulation (DBS) on these nuclei is still unknown, but the most likely explanation is that the damping effect of PD is alleviated by high-frequency stimulation of the STN, while the inverse happens in dystonia, where stimulation of the globus pallidus interna (GPi) dampens the abnormal tone and movements.
