Role of afferent sensors in the initiation of swallowing in man.
Chewing and swallowing sounds that were recorded on magnetic tape by means of a paralaryngeally placed contact microphone were used to evaluate temporal relationships of the events of the swallowing cycle in young women. Temporal inter-event parameters indicate a reflex nature for the initiation of swallowing, and the effects of topical anesthesia suggest a triggering mechanism for swallowing similar to the gating theory for pain proposed by Melzack and Wall.
