Fue galardonado con el Premio Nobel de Fisiología o Medicina en 1904 for research pertaining to the digestive system. Pavlov was widely known for first describing the phenomenon now known as classical conditioning in his experiments with dogs.

He began his higher education as a seminary student, but dropped out and enrolled in the University of St. Petersburg to study the natural sciences. He received his doctorate in 1879. Pavlov’s Dogs, Pavlov Museum, 2005 In the 1890s, Pavlov was investigating the gastric function of ferrets by externalizing a salivary gland so he could collect, measure, and analyze the saliva produced in response to food under different conditions. He noticed that the ferrets tended to salivate before food was actually delivered to their mouths, and set out to investigate this "psychic secretion", as he called it. He decided that this was more interesting than the chemistry of saliva, and changed the focus of his research, carrying out a long series of experiments in which he manipulated the stimuli occurring before the presentation of food. He thereby established the basic laws for the establishment and extinction of what he called "conditional reflexes" — i.e., reflex responses, like salivation, that only occurred conditional upon specific previous experiences of the animal. These experiments were carried out in the 1890s and 1900s, and were known to western scientists through translations of individual accounts, but first became fully available in English in a book published in 1927. Pavlov was a dextrous operator who was compulsive about his working hours and habits. He would sit down to lunch at exactly 12 o'clock, he would go to bed at exactly the same time each evening, would always feed his dogs at exactly the same time each night and he would always leave Saint Petersburg/Leningrad for [Estonia on vacation on the same day each year. This behavior changed when his son Victor died in the White Army. Unlike many pre-revolutionary scientists, Pavlov was highly regarded by the Soviet government, and he was able to continue his researches until he reached a considerable age. Pavlov himself was not favorable towards Marxism, but as a Nobel laureate he was seen as a valuable political asset, and as such was lavishly funded. After the murder of Sergei Kirov in 1934, Pavlov wrote several letters to Molotov criticizing the mass persecutions which followed and asking for the reconsideration of cases pertaining to several people he knew personally. In later life he was particularly interested in trying to use conditioning to establish an experimental model of the induction of neuroses. He died in Leningrad. His laboratory in St Petersburg has been carefully preserved. Legacy Interestingly, Pavlov's term "conditional reflex" ("условный рефлекс") was mistranslated from the Russian as "conditioned reflex", and other scientists reading his work concluded that since such reflexes were conditioned, they must be produced by a process called conditioning. As Pavlov's work became known in the West, particularly through the writings of John B. watson, the idea of "acondicionamiento" as an automatic form of learning became a key concept in the developing specialism of comparative psychology, and the general approach to psychology that underlay it, behaviorism. Bertrand Russell was an enthusiastic advocate of the importance of Pavlov's work for philosophy of mind. It is popularly believed that Pavlov always signaled the occurrence of food by ringing a bell. Sin embargo, his writings record the use of a wide variety of auditory stimuli, including whistles, metronomes, tuning forks, in addition to a range of visual stimuli. When, in the 1990s, it became easier for Western scientists to visit Pavlov's laboratory, no trace of a bell could be found. In observing individual differences in conditioning between his subjects Pavlov developed a typology of higher nervous activity which was the first systematic approach to the psychophysiology of individual differences. His theory was further developed by Teplov, Nebylitsyn and their pupils in the Institute of Psychology in Moscow. These ideas in turn informed Eysenck's theory of the physiological bases of extraversion and introversion and Gray's conception of arousability.
