Table 4 Brain areas indicating changed FC with the cerebellar lobule VIII in the post-taVNS patients compared to the pre-taVNS patients (GRF corrected, voxel p < 0.005, cluster p < 0.05). FC functional connectivity, taVNS transcutaneous auricular vagus nerve stimulation, post-taVNS after taVNS treatment, pre-taVNS before taVNS treatment, GRF Gaussian random field, AAL automated anatomical labeling, MNI Montreal Neurological Institute, SMA supplementary motor area, PoCG postcentral gyrus, L left, R right.
