Emotionally Arousing Visual Stimuli Modulate Oscillatory alpha Activity Recorded from STN Area in PD Patients

High frequency stimulation (HFS) of the subthalamic nucleus (STN) has become a widely accepted therapy to treat motor symptoms in PD patients. In some patients however, stimulation may be accompanied by behavioral and cognitive side effects drawing attention to a possible influence of HFS on associative and limbic circuits within the STN area. To further elucidate the involvement of the human STN region in the processing of emotional information we investigated changes in oscillatory activity within the STN area in response to emotionally arousing visual stimuli. Local field potentials (LFP) were recorded throug…
