Figure 7. Cued recall and category responses are differentially task modulated across S1 and S2.

(A) Population coding of stimulus, cued recall, or category information during the test period analyzed according to the animal’s choice using cross-validation. Performance of a classifier modeled from correct trials are shown upon testing on other correct trials (solid bars) or error trials (open bars). Testing was performed separately for S1 or S2 on either miss trials (left) or false alarm trials (right). (B-D) Comparison of sample recall and category information during the test period under task performance vs. passive stimulation in S1 and S2 cued recall encoding neurons (B), match encoding neurons (C), and non-match encoding neurons (E) are shown. Left panels indicate average time course during the test period for active, passive, and shuffled conditions. Right panels indicate mean across the test period. Error bars: s.e.m.; n = 57 imaged populations (A), 583 S1 neurons, 473 S2 neurons (B), 95 S1 neurons, 102 S2 neurons (C), 454 S1 neurons, 421 S2 neurons (D); * P < 0.05, ** P < 0.02, *** P < 1 x 10⁻³.
