MNI coordinates for the local maxima of clusters with significant voxels (cluster-level corrected p < 0.05).
*
Size refers to volume of cluster, stated in number of voxels (2mm × 2mm × 2mm).
†
The splenium of the corpus callosum was merged with the adjacent precuneus at an uncorrected p < 0.005. NS, not significant; R, right; L, left; M, medial; BA, Brodmann areas; dACC, dorsal anterior cingulate cortex; vlPFG, ventrolateral prefrontal cortex.
