Simultaneous recordings in the STN and GP during STN DBS. A) DBS electrode and contact locations. B) Evoked potentials in the STN, GPi and GPe normalized by their respective maximum amplitudes for comparison of latencies. C) Left: STN DLEPs. Note the high degree of similarity for repeated trials of STN DBS (blue and red or yellow and green). Right: Evoked responses in GPi or GPe to STN DBS. The EPs were different depending on the recording contacts chosen. For all participants see Supplemental Fig. 9. L/R: Recording and stimulation in the left/right hemisphere. GPi/GPe: Simultaneous recording with GP lead selected to record differentially between contacts 0 and 1 (GPi) or contacts 2 and 3 (GPe). All data depicted are from Participant 15.
