Positive sign represents increase, and negative sign represents decrease. HE = hepatic encephalopathy; FDR = false discovery rate; Hem = hemisphere; BA = Brodmann's area; MNI = Montreal Neurological Institute; ΔVol: volume difference; MCC = middle cingulate cortex; SFG = superior frontal gyrus; ACC = anterior cingulate cortex; STG = superior temporal gyrus; IPL = inferior parietal lobule; SMA = supplementary motor area; ITG = inferior temporal gyrus; MFG = middle frontal gyrus.
