The pattern of neuronal discharge within the basal ganglia is disturbed in Parkinson's disease (PD). In particular, there is a tendency for neuronal elements to synchronise at around 20 Hz in the absence of dopaminergic treatment, whereas this activity can be replaced by spontaneous synchronisation at much higher frequencies (>70 Hz) following dopaminergic treatment [J. Neurosci. 21 (2001) 1033; Brain 126 (2003) 2153]. In two PD patients (3 sides), we show that stimulating the subthalamic ...Expand abstract
