Figure 5. Ensemble TRN activity differs only around cue onset during auditory and tactile trials.

Figure 5

(A) Pseudocolor z-score plots comparing dorsolateral (left) and dorsomedial (right) striatal TRN ensemble activity during auditory and tactile trials (as labeled). (B) Mean z-scores and SEMs across task-time for auditory (dark color) and tactile (light color) trials, plotted for each training block for dorsolateral (left, red) and dorsomedial (right, blue) ensembles. (C) Mean z-scores and SEM across all stages for dorsolateral (left) and dorsomedial (right) TRNs during ±300-ms around cue onset, (D) Percentage of units differentiating between auditory and tactile task-versions for dorsolateral (left, red) and dorsomedial (right, blue) TRNs. Dark and light bars indicate percentage of units with higher firing during auditory or tactile conditions, respectively. Solid and dashed black lines indicate percentage of auditory- and tactile-preferring neurons obtained after shuffling trials. (E) Percentages of modality-discriminative TRNs in dorsolateral (red) and dorsomedial (blue) striatal regions, plotted across training stage. (F) Percentage of TRNs responding with significant increases or decreases in firing to the onset of each of the four discriminative stimuli and the warning click in the dorsolateral (red) and the dorsomedial (blue) striatum. Dashed line indicates percentage expected by chance. See also Figure S5.
