Regions characterized by dACC hyper-modulation during both Periodic and Random conditions are shown. These clusters are based on a union of the clusters sets in Figures 2 and 3 and depict common patterns of hyper-modulation in the anterior cingulate cortex (ACC), insula (Ins), superior temporal gyrus (STG), putamen (Put), thalamus (Thal), posterior cingulate cortex (PCC), and cingulate gyrus (CG).
