Two-block pavlovian task and behavioral responses. A, In the appetitive block (left), juice was delivered as US. In the aversive block (right), airpuff was delivered as US. In each block, three visual stimuli were used as CS, which predicted US with the probabilities of 100, 50, and 0%. B, Normalized (z-scored) magnitude of licking (top) and blinking (bottom) during the CS epoch in the appetitive (left) and aversive (right) blocks. Vertical bars indicate the mean ± SEM (from single trial z-scores across 152 recording sessions). Licking was correlated to the probability of reward during the appetitive block (ρ = 0.33; p < 0.01). Blinking was correlated to the probability of punishment during the aversive block (ρ = 0.25; p < 0.01). The correlations were performed on single trial z-scores across 152 recording sessions.
