Ventral striatal responses to RL and belief prediction errors. (A) Coronal sections and glass brain of putamen activation to the RL prediction error (P < 0.001 uncorrected, cluster size k ≥ 20). (B) Significant activation of bilateral putamen and ventral caudate to the belief prediction error for the chosen action (P < 0.001 uncorrected, k ≥ 20). (C) Region of interest analyses show that activities in bilateral ventral striatum (Table 1) were significantly correlated with both RL and belief prediction errors; error bars indicate SEM.
