Figure 2. Ensemble neural activity differs between dorsolateral and dorsomedial striatal recording sites during T-maze training.

Figure 2

(A) Ensemble z-score plots illustrating population activity across trial time and training stages for dorsolateral (top) and dorsomedial (bottom) TRNs. Scale for both plots shown in center. Numbers to the right of each row indicate the number of units included in that stage. (B and C) Mean z-scores (solid lines) and SEMs (shaded) plotted across task time for dorsolateral (red) and dorsomedial (blue) TRNs separately (B) and overlaid (C) for successive phases of training. Task events abbreviated as: BL = baseline (1 sec prior to warning click); W = warning click; Ga = gate opening; L = locomotion onset; S = out of start; C = cue onset; TS = turn start; TE = turn end; Go = goal reaching. Gray dots in C indicate significant difference between dorsolateral and dorsomedial activity during the corresponding 20-ms bin (p < 0.01, t-test). See also Table 1 and Figure S2.
