FC of brain areas with abnormal ALFF values was compared with that in other brain areas between the CADASIL and control groups. a The CADASIL group had weaker FC between the left SFG and right precentral gyrus and between the left SFG and bilateral pons. b Weaker FC between the right SFG and right precentral gyrus and between the right SFG and left postcentral gyrus was observed in the CADASIL group compared to the control group. c The patients with CADASIL displayed significantly weaker FC between the right Pcu/CU and right CU and between the right Pcu/CU and right PHG. The color-coded scale was referred to the t-values. FC: functional connectivity; ALFF: amplitude of low-frequency fluctuation; CADASIL: cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy; SFG: superior frontal gyrus; Pcu/CU: precuneus and cuneus; CU: cuneus; PHG: parahippocampal gyrus
