Coordinates of activation foci together with Z scores and an estimate of location relative to gross anatomy for each contrast of interest. SFG, Superior frontal gyrus; MTG, middle temporal gyrus; V Str., ventral striatum; R, right; L, left. All peak voxels exceeding p < 0.001 are reported (at least 10 voxels clusters). Each area may be composed of one or several clusters.
