Regions associated with goal value, decision value, and prediction error. For time courses in a–c, high values are shown with circular markers connected by solid lines. Low values are marked by triangles connected by dotted lines. Markers represent the mean β value from a finite impulse response model at each time point. Error bars represent the SEM. Asterisks indicate points in time where there is a significant difference between high and low based on paired t tests at p < 0.05. Activation maps in d, e, and f are shown at a threshold of p < 0.005 uncorrected and an extent threshold of 10 voxels. Voxels in red are significant at p < 0.005 uncorrected, whereas voxels in yellow remain significant at p < 0.0001 uncorrected. d, Activity in the OFC and anterior cingulate cortex correlated with goal value. e, Activity in the central OFC correlated with decision value. f, Activity in the ventral striatum correlated with prediction error. g–o, Bar graphs represent the mean β value ± SE at high (HH), medium high (MH), medium low (ML), and low (LL) levels of GV, DV, and PE. The p values displayed in the bar graphs were determined based on paired t tests between high and low trials. Bars in black show the value that best fits each region.
