Figure 2. — Value and update signals in the brain: whole-brain analysis. A, Activity in striatum correlated with the reward expectancy ratings provided by the participants at the beginning of each trial. B, Activity in a dorsal region of the vmPFC correlated with reward magnitude during the outcome period of reinforced trials. C, Activity in a ventral region of the vmPFC exhibited a stronger response to color A compared to color B during late reversal (ie, stronger response to the old CS+, which ceased to predict reward after the contingency switch, compared to the new CS+). Activations are overlaid on an average anatomical image of all participants. p < 0.005 voxel-level threshold and p < 0.05 cluster-size corrected.
