Figure 4

Mean ± s.em. responding to the cues A (panel A) and C (panel B) in the test phase of Experiment 1. Cues A and C had each been paired with food in the initial conditioning phase. In the compound training phase, rats in the Over condition received reinforced AC compound presentations intended to produce an overexpectation of food (negative prediction error), whereas rats in the CTL condition received reinforced BC compound presentations, intended to produce little prediction error. The overexpectation phenomenon is indicated by lower responding to A and C after the Over treatment than after the CTL treatment. CeA = rats with lesions of amygdala central nucleus; BLA = rats with lesions of basolateral amygdala.
