PAVLOV, Ivan Petrovich.

Fine copy, signed by the first owner and with Pavlov's own inscription tipped-in 'V polne odobryayu. 8 Yunya 1935. I. Pavlov [I fully agree confirm. 8 June 1935]'.
In 1903 Pavlov made the first public statement on the conditioned reflex, and was awarded the Nobel Prize of medicine in 1905. He later broadened his research, gaining a deep insight in the subject over the following twenty years, based on his experimental research into the relation between the nervous system, the brain, and behaviour. Extending experimental physiology into psychology, he and his team laid the foundations of the behaviourist school. 'In recent years he has come to be regarded as a mechanist who saw complex behaviour as the sum of individual conditioned reflexes. This is a profound error, since in Pavlov's view the brain, through its capacity for subtle analysis and complex synthesis, integrates a vast range of conditioned reflexes into coherent corresponding to the specific circumstances and needs of the organism' (DSB). Pavlov's research institute is depicted in this third edition with photos and plans.
