a–c, Heatmaps of the OFC neurons showing epoch-specific (a), reward-specific (b) and position-specific (c) firing in the figure-of-eight task. In each panel, the heatmap shows average activity in each epoch at each position in one maze. Individual squares corresponding to each epoch are magnified in the black dashed box at the top. Arrows represent sequence directions. A red asterisk marks the reward epoch on rewarded trial types (P3 and P4), whereas a black asterisk marks the reward epoch for nonrewarded trial types (P1 and P2). d–f, Plots show the percentage of the OFC neurons with firing that was significantly modulated by epoch (d), reward (e) and position (f) (ANOVA, P < 0.01), with each neuron assigned to the condition of maximal firing. There were no effects of inactivation (χ2 < 1.42; P > 0.23; degree of freedom (d.f.) = 1; χ2 test). Red denotes the chance level.
