ACC, anterior cingulate cortex; AG, angular gyrus; ASN, anterior salience network; AUD, alcohol use disorder group; Cau, caudate; CI, crus I; CII, crus II; DDMN, dorsal default mode network; HC, healthy control group; Hip, hippocampus; INS, insula; IPG, inferior parietal gyrus; L, left; LIX, lobule IX; LVI, lobule VI; MCC, midcingulate cortex; MFG, middle frontal gyrus; mPFC, medial prefrontal cortex; MOG, middle occipital gyrus; PC, precuneus; PCC, posterior cingulate cortex; PHG, parahippocampal gyrus; PSN, posterior salience network; R, right; RC, restrosplenial cortex; RECN, right executive control network; SFG, superior frontal gyrus; SMA, supplementary motor area; SMG, supramarginal gyrus; SPG, superior parietal gyrus; Th, thalamus; VDMN, ventral default mode network. The italicized regions showed the reductions of gray matter volume among AUD group.
