Fig. 4.
Group random-effects results are shown for the correlation with relative subjective value (i.e., SVASAPg=1) in the NOW (top) or 60 DAY (middle) condition and for the difference in mean activity between the NOW and 60 DAY conditions (bottom). Each contrast is for time points 4–6 in the trial, which corresponds to a neural effect at the time both options are shown. Maps are thresholded at P < 0.005 (uncorrected), with a spatial extent threshold determined for each map so that cluster-level inference is at P < 0.05 (corrected). Ventral striatum (coronal) and medial prefrontal and posterior cingulate cortex (sagittal) all exhibited a significant correlation with relative subjective value in the NOW condition, but no significant correlation in the 60 DAY condition and no significant differences in mean activity.
