L, Left; R, right; Hip, hippocampus; paraHip, parahippocampus; MFG, middle frontal gyrus.

a Coordinates in Talairach space (x, left to right; y, posterior to anterior; z, inferior to superior).

b Regions of the valuation process: positive correlation with money magnitude; negative correlation with time delay; threshold at uncorrected p < 0.005, cluster size 160 mm3. Regions of the choice process: larger activation in hard trials than in easy trials; threshold at uncorrected p < 0.005, cluster size 424 mm3, corrected p < 0.05.

c Segmented regions.
