It is widely assumed that there is a functional relationship in squamates between flicking of the tongue and delivery of chemical cues to the vomeronasal system (VNS; see Young, 1993), Electrophysiological data have demonstrated a close temporal correlation between the activity pattern of the tongue retractor system and stimulation of the sensory receptors in the vomeronasal organs (VNO; Meredith & Burghardt, 1978).
