Note. L and R refer to left and right hemispheres; x y and z refer to MNI coordinates; Max Z refers to the z-score at those coordinates (local maxima); k refers to the number of voxels in each significant cluster. Anatomical regions that share functional clusters are denoted with the same superscript letter. All regions are listed at cluster-forming threshold of Z>2.3 and an extent threshold of p<.05 corrected using the theory of Gaussian random fields. The following abbreviations were used for the specific brain regions: dACC=dorsal anterior cingulate cortex; VS=ventral striatum; DS=dorsal striatum; DLPFC=dorsolateral prefrontal cortex.
