Significant differences by commodity type in functionally defined regions of interest identified using a disjunction mask. Extraction Type I error rates were familywise p <.005 + cluster size ≥5 voxels (voxelwise p <.000016). Money = Money choices; Cig = cigarette choices; SEM = standard error of the mean; L = left, R = right. Coordinates are in Talairach space. Significant effects are in boldface.
