Lesions encompassing areas 11 and 13 disrupt credit assignment. A) Monkeys perform a three-arm bandit task with changing probabilities. Colored points represent the stimulus (stimulus A-C) associated with the highest probability of reward on a given trial. Curves show mean probability of selecting the stimulus associated with the highest probability of reward (H Choice) where the probability of reward associated with the three options changed within a session. Shaded regions represent the SEM for each group. OFC group: dashed line and blue shaded region; unoperated controls: solid line and grey shaded region. B) Mean probability of selecting the stimulus associated with the highest probability of reward (H choice) when the difference in probability of reward between options is large (left) and small (right). Shaded regions represent the SEM associated with each group. OFC group: dashed line and blue shaded region; unoperated controls: solid line and grey shaded region. Colored points in the Task Schedule above each graph show reward probabilities associated with each stimulus (stimulus A-C). A) adapted from Rudebeck et al. (2008) and B) adapted from Walton et al.
