Figure 6. — Impact of STN high-frequency stimulation at low intensity on the pattern of responses evoked by cortical stimulation in a SNR cell. A, Triphasic excitatory–inhibitory–excitatory pattern of response evoked by stimulation of the orofacial sensorimotor cortex while the STN stimulation is turned off. B, During the STN high-frequency stimulation (130 Hz) at low intensity (2.8 V) that produced a marked inhibition of the cell activity, responses evoked by cortical stimulation presented a similar pattern, although excitations were decreased; inset, inhibitory effect of STN high-frequency stimulation on the spontaneous activity of the recorded SNR cell. Arrows indicate the time of stimulation.
