Table 2 Comparisons of the vlPAG functional connectivity change in 1 Hz and 20 Hz taVNS

From: Different modulation effects of 1 Hz and 20 Hz transcutaneous auricular vagus nerve stimulation on the functional connectivity of the periaqueductal gray in patients with migraine

Comparisons Brain Regions Cluster size (voxel number) Peak T MNI coordinates
x y z
1 Hz taVNS > pre-resting MCC 282 6.36 − 4 − 12 40
PCu 200 4.71 4 − 50 44
MFG 232 4.56 − 30 30 42
Cuneus 191 4.05 − 6 − 76 32
pre-resting > 1 Hz taVNS  
20 Hz taVNS > pre-resting No regions survive the threshold
pre-resting > 20 Hz taVNS  
  1. “Pre-resting” indicated pre-taVNS resting-state. Results were significant at cluster pFDR < 0.05, corrected at the whole brain level
  2. vlPAG ventrolateral periaqueductal gray, MCC middle cingulate cortex, PCu precuneus, MFG middle frontal gyrus
