Altered effective connectivity to and from the right PTH in MWCA compared with HC (a) and MWoCA (b) (voxel-level P < 0.01 and cluster-level P < 0.05, Gaussian random field corrected) respectively. Compared with HC, MWCA showed increased inflow to R_PTH from the bilateral STG, SMG, IPL, IFG, and MFG, and decreased outflow to the same regions (a). Compared with MWoCA, MWCA showed increased inflow from the OC and caudate to the R_PTH (b). HC, healthy control; IFG, inferior frontal gyrus; IPL, inferior parietal lobule; MFG, middle frontal gyrus; MWCA, migraineurs with cutaneous allodynia; MWoCA, migraineurs without cutaneous allodynia; OC, olfactory cortex; PTH, posterior thalamus; R_PTH, right posterior thalamus; SMG, supramarginal gyrus; STG, superior temporal gyrus
