dACC, dorsal anterior cingulate cortex; daINS, dorsal anterior insular; IFG, inferior frontal gyrus; rIPL, right inferior parietal lobe; MOG, middle occipital gyrus; MPFC, medial prefrontal cortex; MTG, middle temporal gyrus; SOG, superior occipital gyrus; MCC, middle cingulate cortex; SMA, supplementary motor area; DLPFC, dorsolateral prefrontal cortex. Results are thresholded with voxel-level p < 0.001 uncorrected and cluster-level whole-brain p < 0.05 FWE correction.
