Transcutaneous auricular vagus nerve stimulation at 1 Hz modulates locus coeruleus activity and resting state functional connectivity in patients with migraine: An fMRI study.
“Our results suggest that taVNS at 1 Hz can significantly modulate activity/connectivity of brain regions associated with the vagus nerve central pathway and pain modulation system, which may shed light on the neural mechanisms underlying taVNS treatment of migraine.” This study
