Fig. 7.
Firing patterns of STN, GPe and GPi neurons. Rastergrams and interspike interval (ISI) plots under normal, PD, and PD condition with 130 Hz STN DBS. During the PD state, neurons fired in a more rhythmic burst fashion, while 130 Hz STN DBS suppressed these bursts by either exciting or inhibiting the firing of GPe/GPi neurons
