Note: L and R refer to left and right hemispheres; k refers to the number of voxels in each significant cluster; t refers to peak activation level in each cluster; and x, y, and z refer to MNI coordinates. Regions that share the same superscript are part of the same cluster. The mPFC was small volume corrected, which yielded a minimum cluster size of 20 for neural activation and 18 for coactivation (PPI). All other regions were based on a whole-brain mask, which yielded a minimum cluster size of 116 voxels for neural activation and 74 voxels for coactivation (PPI). All regions are significant at p < .005.
