Transcutaneous auricular vagus nerve stimulation at 1 Hz modulates locus coeruleus activity and resting state functional connectivity in patients with migraine: An fMRI studysciencedirect.com
- Study explores the process of relieving migraine with electrostimulation of vagus nerve (longest nerve in our bodies) endings in the ear.
- Transcutaneous auricular vagus nerve stimulation (taVNS) at 1hz can prevent migraines, but it was previously unknown how it happens.
- Researchers regularly scanned the brains of 29 patients, and analysis showed taVNS at 1hz changes the activity and connectivity of certain brain regions.
- These regions are associated with the pain modulation system, and further studies are required to fully understand the neural mechanisms that make taVNS effective.
