Values are correlation coefficients unless indicated otherwise. The italicized regions showed the reductions of gray matter volume among AUD group. ACC, anterior cingulate cortex; AG, angular gyrus; ASN, anterior salience network; AUD, alcohol use disorder group; DDMN, dorsal default mode network; HC, healthy control group; INS, insula; IPG, inferior parietal gyrus; Hip, hippocampus; L, left; MFG, middle frontal gyrus; mPFC, medial prefrontal cortex; MOG, middle occipital gyrus; PHG, parahippocampal gyrus; PI, posterior insula; PSN, posterior salience network; R, right; RECN, right executive control network; SFG, superior frontal gyrus; SMA, supplementary motor area; SMG, supramarginal gyrus; Th, thalamus; VDMN, ventral default mode network.
