This paper provides a narrative review of tcVNS and taVNS stimulation. While both target the same cranial nerve, they differ significantly in their anatomical access points and methodological implementations.<\/jats:p>","DOI":"10.3389\/fnins.2026.1848801","type":"journal-article","created":{"date-parts":[[2026,7,15]],"date-time":"2026-07-15T15:01:11Z","timestamp":1784127671000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Two paths to the body\u2019s superhighway\u2014the auricular branch (taVNS) and the cervical bundle (tcVNS): a narrative review"],"prefix":"10.3389","volume":"20","author":[{"given":"Peter S.","family":"Staats","sequence":"first","affiliation":[{"name":"Vagus Nerve Society","place":["Atlantic Beach, FL, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justyna","family":"Blake","sequence":"additional","affiliation":[{"name":"electroCore","place":["Inc.
