P-value (P < 0.01, FDR-corrected). iRBD, isolated rapid eye movement sleep behavior disorder; HCs, healthy controls; MCG, middle cingulum gyrus; LING, lingual gyrus; SOG, superior occipital gyrus; MOG, middle occipital gyrus; PoCG, postcentral gyrus; SMG, supramarginal gyrus; IFG-triang, inferior frontal triangular gyrus; PCL, central paracentral lobule; SMA, superior motor area. Regions are considered abnormal in the iRBD patients if they exhibited significant between-group differences in at least one of the three nodal centralities (shown in bold font).
