Non-invasive access to the vagus nerve central projections via electrical stimulation of the external ear: fMRI evidence in humans
Frangos E, Ellrich J, Komisaruk BR
Brain Stimulation · 2015
Key finding
Electrical stimulation of the cymba conchae activated classical central vagal projections including the NTS, locus coeruleus, and dorsal raphe, providing fMRI evidence that vagal afferents can be accessed non-invasively via the external ear.
