Shown is each cluster and subclusters of significant peak activations (Z > 2.3). The coordinates (mm3) are within standard Montreal Neurological Institute stereotaxic space (MNI) of the peak voxel within that cluster.
L, left, R, right.
*The peak regions of activation in the subclusters of the right and left ventral striatum and global pallidus were manually identified.
