Subthalamic task-related LFP activity. (a) Trial-averaged time-frequency charts of a STN bipolar recording in a representative patient. Time origin indicates stop cue during SS and US trials and button press during GO trials. (b) Single-trial beta band power of a STN bipolar recording time-locked to stop cue during SS and US trials and to virtual stop cue during GO trials. (c) Grand average beta power time series (n=7 patients, 14 recorded STNs). (d) Beta band maximal power amplitude in the 500-ms period after stop (or virtual stop) cue. Vertical dashed orange line indicates the average latency at which the difference between SS and LMGO trials reached significance. Vertical dashed red line indicates SSRT. Stars indicate significant differences between trial types (post hoc Tukey, P<0.05). LFP, local field potential; LMGO, latency-matched GO; SS, successful stop trial; SSRT, stop-signal reaction time; STN, subthalamic nucleus; US, unsuccessful stop trial.
