The functional indicators in the brain regions. (Alcohol dependence < HCs, relapse < nonrelapse). Compared to the HCs, the alcohol dependence group had decreased ReHo in the left postcentral (a), left precentral (b), right postcentral (c) and right precentral (d); decreased fALFF in the left postcentral (e), right precentral (f), right postcentral (g) and fusiform (h); decreased FCs of the left precentral (seed) with the right lingual (i), left middle cingulum (j) and left insula (k); decreased FCs of the right precentral (seed) with the right lingual (l), right insula (m) and left superior temporal (n); decreased FC of the left postcentral (seed) with left insula (o); decreased FC of the right postcentral (seed) with the left superior temporal (p); and decreased FC of the right fusiform (seed) with the right middle cingulum (q). The T map was drawn with P < 0.001 at the voxel level and PFWE < 0.05 at the cluster level
Compared to the nonrelapse group, the relapse group had: decreased FC of the left precentral (seed) with the left cerebellum (r, s, t). (P < 0.002 at the voxel level, PFWE < 0.05 at the cluster level). The color bar represents the voxel T value. HCs: healthy controls. ReHo: reginal homogeneity. fALFF: fractional amplitude of low-frequency fluctuations. FCs: functional connectivities.
