Background Information

Born: September 14, 1849 Birthplace: Ryazan, Russia Education: Attended Ryazan Ecclesiastical

Seminary for several years, dropped out and enrolled at the University of St. Petersburg. Earned his doctorate (equivalent to a Bachelor's Degree) in 1879

Death: February 27, 1936

As a child Pavlov loved to garden, to ride his bicycle, row, swim and play gorodki.Ivan Pavlov began his higher education at the Ryazan Church School at the age of 11.In 1870, Pavlov left for St. Petersburg without finishing the seminary. He enrolled in the physics and math department, taking the natural science course. In his fourth year at the university, he made his first research and won a gold medal. his research concerned the physiology of the nerves of the pancreas.In 1878, Professor S.P. Botkin, a famous Russian clinician, invited the gifted young physiologist to work in the physiological laboratory at his clinic as its chief. In 1879 Pavlov graduated from the Medical Military Academy with an award of a gold medal for his research work. After a competitive examination, Pavlov won a fellowship at the Academy for postgraduate work.

The Beginning.... Pavlov was planning to study saliva (which he

received from dogs), collect normal data and see the reaction it had on certain foods.

While attempting to collect saliva from dogs he noticed that the dogs tended to pro

He called this phenomenon “psychic secretion" His attention then turned from saliva to

behaviorism.

Ivan Pavlov discovered Classical conditioning.Ivan Pavlov wrote two books;Lectures on the Work of the Digestive Glands (1897) Conditioned Reflexes: An Investigation of the Physiological Activity of the Cerebral Cortex (1927)

His Experiments…

Pavlov determined to discover the roots of this phenomenon.

He did series of experiments where he rang a bell just before he served the dog food

He called these reflex produced by the stimulus (in this case the bell and food served afterward) “conditional reflexes”.

Conditional Reflexes

Once satisfied with his experiments, Pavlov establish the basic rules of “conditional reflexes”

He stated that conditional reflexes can only occur when responses become automatic after several experiences where the condition (Pavlov's case was the bell) occurs

Even after Pavlov's discovery his experiments and findings wouldn't be published in English until 1927

The Experiment of his death...?

On the day of his death, Pavlov asked one of his students to stay by his bed side and record the conditions of his death

It's believe Pavlov wanted to create evidence of particular experiences in one's last moments in life

It takes a great scientist to want to increase their knowledge on their death bed.

It's almost incredible to believe he was son of a village priest and who's mother was daughter of a priest. He seemed destined to end up preaching just as his father, but out came this great man who studied extensively the digestive system of both humans and animals and deserve the recognition he's received.

Through Pavlov's extensive research and experiments he managed to win himself the 1904 Nobel Prize in Physiology and Medicine for successfully extracting digestive organs out of animals.

A great man was he who spoke these words “Don't become a mere recorder of facts, but try to penetrate the mystery of their origin.”
