Expanded definition
Auricular VNS is often used as a plain-language category. When electrical stimulation is delivered through the skin, the more precise research term may be transcutaneous auricular vagus nerve stimulation, or taVNS.
The outer ear is not innervated by one nerve alone. Anatomical overlap, individual variation, electrode position, and stimulation parameters all matter when interpreting a protocol.
Because the phrase can be used broadly, responsible writing should state the exact ear location, delivery method, device, and intended use whenever those details are known.
What the term does not establish
Why the distinction matters
The term is useful for readers, while taVNS and exact placement details provide the precision needed for research interpretation.
