Experiment 1: the number of lever presses and chain pulls (i.e., actions) per minute during instrumental training (left panel) and during the choice extinction test conducted after one of the training outcomes was devalued by a specific satiety treatment. Data from the extinction test are presented for group Sham (center panel) and group BLA (right panel) averaged across 2 min periods with performance of the action that previously delivered the prefed, i.e.,Devalued, outcome (●) presented separately from performance of the action that had delivered the non-prefed, i.e.,Valued, outcome (○) for each group.
