When the condition is not met - that is, when food does not regularly follow - reflexive salivation stops; the conditional reflex is inhibited. Salivation is largely controlled by the salivary centre, located in the medulla and pons, through the autonomic nervous system. For example, the sound of the food dispenser may function concurrently as elicitor of conditioned salivation and conditioned reinforcer for lever presses.

Characterization of both behavioural and chemical aspects of aphid salivation are important for a better understanding of the mechanisms involved in aphid-plant interactions. With repetition of light followed by food, salivation begins just before the usual time that food appears. The acquired reflex is fired in the absence of any form of oral stimulation; simply thinking about, seeing or smelling food will cause abundant salivation. Salivation, swallowing, freezing and sensory complaints were not evaluated. Eating foods that require active chewing will promote salivation,29,48 thus reducing the incidence of taste abnormalities. Several reasons for salivation into sieve elements have been reported. In addition to measuring bar-pressing, the dogs were surgically prepared so that salivation could be monitored. Dehydration, lack of sleep and fear provide examples of factors that may inhibit salivation. These examples are from corpora and from sources on the web.
