Fig. 3: S2 Population coding dynamics during the TPDT and LCT.

a–b Percentage of neurons with significant coding (see Supplementary Fig. 3) as a function of time during the TPDT (n = 1646) and the LCT (n = 313). Traces refer to P1 (cyan), P2 (green), all class coding (pink), and decision coding (black). Note that P1 working memory, decision, and class coding essentially vanished during the LCT: instead, the coding was restricted to stimulus periods in the LCT. Similar to frontal lobe areas, all categorical and perceptual codes are abolished during the control, but akin to S1, S2 sensory responses always persist (see Supplementary Fig. 4).
