Functionally connected clusters as indicated by a seed region of interest (ROI) prescribed in the ventral anterior cingulate cortex and adjusting for the effects of age and total gray matter volume, and results of voxel-wise within-group analyses of z-transformed functional connectivity values while accounting for the effects of age and total gray matter volume.
