"Pavlov made perhaps the greatest contribution to our knowledge of the physiology of digestion"--Garrison and Morton. "Pavlov could not help but see the 'psychic' stimulation of the salivary glands as a phenomenon analogous to the normal digestive reflex. Both digestion and salivation were reflexive; only the external agents that evoked the reflexes were different. The digestive reflex was triggered by the essential mechanical and chemical properties of the food; the salivary by nonphysiological 'signals', including the form and odor of the food. Using the concept of the reflex as an elementary response of the organism to external stimulus, Pavlov termed the normal digestive reaction an unconditioned reflex, and the activity of the salivary glands, stimulated by various environmental agents, a conditioned reflex."--Dictionary of Scientific Biography.
