Subthalamic nucleus (STN) evoked response. A representative single subject demonstrates the EEG evoked response in each of the nine regions of interest to low frequency right STN stimulation for each of the four lead contacts. It can also be observed that the signal arises slightly before stimulus onset. Rather than a detection error, this results from the effect of the filter on the interpolated signal, which replaced the stimulus artifact. DLR, dorso-lateral region; VMR, ventro-medial region.
