The table shows brain areas and corresponding Brodmann areas (BA) in regions of interest (ROIs), co-ordinates in Montreal Neurological Institute (MNI) space (x, y, z), cluster p-value (Family Wise Error, FWE, corrected), peak p-value (FWE corrected), and the number of activated voxels (#). ACC, anterior cingulate cortex; DLPFC, dorsolateral prefrontal cortex; PPC, posterior parietal cortex.
