A, Effect of decision variables in striatum. BOLD activity positively correlates with Rc and −Ru (p < 0.05) but not with −Qc or Qu, even at a loose threshold [p = 0.01, uncorrected (unc)]. The dotted boxes surround the pairs of effects expected to be significant for value-based learning [Rc − Qc and −(Ru − Qu)] and the solid box surrounds those for policy learning (Rc − κRu). B, Similar activities (bilateral insula, anterior cingulate cortex, and dorsolateral prefrontal cortex) were positively correlated with −Rc and Ru (p < 0.05).
