Figure 7.

Behavioral analysis between intertic and tic periods. A–D, Examples of raw collapsed EMG traces from an injection day when arm and orofacial tics were present. The data are aligned with the onset of tic-related LFP spikes (red trace) and intertic LFP spikes (black trace) in the striatum. Note that there is no detectable EMG voltage deflection in the intertic interval. E, Probability of a spontaneous movement occurring just before and after intertic LFP spikes. Note the lack of consistent probability increases associated with intertic LFP spikes.
