Brain regions indicating reduced seed-based FC between the post- and pre-taVNS patients (GRF corrected, voxel p < 0.005, cluster p < 0.05). The cool color bar represents areas where the FC of the post-taVNS patients is smaller than the pre-taVNS patients. FC functional connectivity, taVNS transcutaneous auricular vagus nerve stimulation, post-taVNS after taVNS treatment, pre-taVNS before taVNS treatment, MwoA migraine without aura, GRF Gaussian random field, SMA supplementary motor area, PoCG postcentral gyrus, R right, L left.
