  4. 4. As a child Pavlov loved to garden, to ride his bicycle, row, swim andplay gorodki.Ivan Pavlov began his higher education at the Ryazan Church School at theage of 11.In 1870, Pavlov left for St. Petersburg without finishing the seminary. Heenrolled in the physics and math department, taking the natural sciencecourse.In his fourth year at the university, he made his first research and won agold medal. his research concerned the physiology of the nerves of thepancreas.In 1878, Professor S.P. Botkin, a famous Russian clinician, invited the giftedyoung physiologist to work in the physiological laboratory at his clinic as itschief. In 1879 Pavlov graduated from the Medical Military Academy with anaward of a gold medal for his research work. After a competitiveexamination, Pavlov won a fellowship at the Academy for postgraduate work.
  5. 5. 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.
  6. 6. Ivan Pavlov discovered Classical conditioning.Ivan Pavlov wrote two books;Lectures on the Work of the Digestive Glands (1897)Conditioned Reflexes: An Investigation of thePhysiological Activity of the Cerebral Cortex (1927)
  7. 7. 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”.
  8. 8. 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 (Pavlovs case was the bell) occurs  Even after Pavlovs discovery his experiments and findings wouldnt be published in English until 1927
  9. 9. 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 Its believe Pavlov wanted to create evidence of particular experiences in ones last moments in life It takes a great scientist to want to increase their knowledge on their death bed.
  10. 10. Its almost incredible to believe he was son of avillage priest and whos mother was daughter of a priest.He seemed destined to end up preaching just as hisfather, but out came this great man who studiedextensively the digestive system of both humans andanimals and deserve the recognition hes received. Through Pavlovs extensive research andexperiments he managed to win himself the 1904 NobelPrize in Physiology and Medicine for successfullyextracting digestive organs out of animals. A great man was he who spoke these words “Dontbecome a mere recorder of facts, but try to penetratethe mystery of their origin.”
