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. 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. This behavior changed when his son Victor died in the White Army. 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. Pavlov was a dextrous operator who was compulsive about his working hours and habits. 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. 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.

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 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. 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.
Petersburg to study the natural sciences. He began his higher education as a seminary student, but dropped out and enrolled in the University of St.
