Ivan Petrovich Pavlov (1849-1936), was a Russian and Soviet experimental neurologist, psychologist and physiologist known for his discovery of classical conditioning through his experiments with dogs.

Pavlov was awarded the Nobel Prize in Physiology or Medicine in 1904 for his studies of the physiology of digestion, which revealed the part that the nervous system plays in controlling digestive secretions. In conducting his physiological researches, Pavlov introduced the method of long-term or continuous experimentation, which—in contrast with traditional vivisectional methods—allowed him to study the operation of physiological processes in healthy animals under normal conditions over extended periods of time. His investigations of the nervous system’s role in digestion led him to explore the phenomenon of “psychic” stimulation; i.e., salivary secretion prompted by the sight or smell of food rather than by direct contact. In Pavlov’s hands this became a powerful tool for investigating the functions of the cerebral cortex and the physiology of behavior. The most famous outcome of his researches is, of course, the artificial conditioned reflex, in which physiological processes such as salivation are arbitrarily associated with stimuli such as the ringing of a bell.

Pavlov presented this offprint, discussing a new laboratory for studying conditioned reflexes, to the British physiologist Ernest Henry Starling, co-discoverer (with Bayliss) of pancreatic secretin and co-developer (again with Bayliss) of the theory of hormonal control of internal secretion. Pavlov had been a strong advocate of the “nervist” doctrine of physiology, which held that the nervous system controlled most body activities; however, Starling and Bayliss’s discovery of secretin, which confirmed the humoral (rather than nervous) transmission of impulses from the intestine to the pancreas, forced Pavlov to rework his theories of digestion (see Babkin, Pavlov, pp. 228-230). ----- Magill, The Nobel Prize Winners: Physiology or Medicine, pp. 61-68.
