(a) Localization of DBS electrodes contacts on axial and coronal MRI sections of a patient. (b) Microelectrode STN recording and mean waveform (black)±s.d. (gray) of the isolated spike cluster. (c) Stop-signal task. Participants were instructed to respond as fast as they can to the GO cue and to withhold their response when a stop signal occurs. Task difficulty during STOP trials was adjusted by shortening or lengthening the delay between GO and STOP cues (stop-signal delay, SSD) after unsuccessful or successful STOP trials. After each trial, positive and negative feedback was presented for 1 s (see Materials and Methods). CD, caudate nucleus; DBS, deep brain stimulation; GP, globus pallidus; MRI, magnetic resonance imaging; RN, red nucleus; SN, substantia nigra; STN, subthalamic nucleus.
