Between 1891 and 1900 Pavlov showed that the nervous system dominates the regulation of digestion, using a chronic experimental method. He noticed that dogs produced saliva in response to food-related cues, concluded this was a learned, temporary reflex, and later found that any outside stimulus paired in time with an ordinary reflex could become a signal for a new conditioned reflex.
