Abbreviations: MOG = middle occipital gyrus; IFGpo/AI = inferior frontal gyrus pars opercularis/anterior insula; IPL = inferior parietal lobule; ACC/MCC = anterior/middle cingulate cortex; MTG = middle temporal gyrus; OG = occipital gyrus; SFG/MFG = superior/middle frontal gyrus; pre‐SMA = presupplementary motor area. ^ = peak voxel p value. L = Left; R = Right; pos. = positive correlation; neg. = negative correlation.
