The clusters located in the cerebellum are not reported. AAL: automated anatomical labeling; MNI: Montreal Neurological Institute; SupraMarginal_R: right supramarginal gyrus; Frontal_Mid_R: right medial frontal gyrus; Caudate_R: right caudate; Caudate_L: left caudate; ALFF: amplitude of low frequency fluctuation; fALFF: fractional amplitude of low frequency fluctuation.
