The antihelix is an arched projection seen on the auricle and situated in front of the posterior part of the helix. The sensory innervation of the auricle is provided by the great auricular nerve (originating from cervical plexus) supplying the helix, antihelix and lobule of the auricle; the lesser occipital nerve (also from cervical plexus) supplying the superior part of the cranial surface of the auricle; the auriculotemporal nerve (a branch of the mandibular nerve) innervating the tragus, the crus and the adjacent part of the helix; and the auricular branch of the vagus nerve (CN X) together with the posterior auricular branch of the facial nerve (CN VII) supplying small areas of the auricle, innervating the concha, as well as the posterior and superior parts of the eminentia of the concha, which is present on the posterior surface of the auricle. This paper, "Effects of Transcutaneous Vagus Nerve Stimulation in Individuals Aged 55 Years or Above: Potential Benefits of Daily Stimulation," was published July 30 in the journal Aging.
