Local field potential (LFP) gamma (55–95 Hz) activity has been recorded in the vicinity of the subthalamic nucleus with both microelectrodes and macroelectrodes in patients with Parkinson's disease undergoing functional neurosurgery. Although this activity increases with movement its functional significance remains unknown. We hypothesised that elevations in local gamma activity might be associated...
Depth recordings in patients with Parkinson's disease (PD) have demonstrated oscillatory activity in the gamma frequency (60–100 Hz) band in local field potentials (LFPs) recorded from the region of the subthalamic nucleus (STN). Although this activity has been hypothesised to contribute to movement preparation, it is unclear to what extent these LFP oscillations arise in the STN and are synchronous...
