"Thanks to our recent works, the physiology of the brain has been advanced to a new stage, and the study of the highest part of the nervous system, which is of such colossal importance to man, has been placed on a solid foundation of exact knowledge."
— from Nobel Lecture, 1904
"One can truly say that the irresistible progress of natural science since the time of Galileo has made its first halt before the study of the higher parts of the brain, the organ of the most complicated relations of the animal to the external world."
— from Scientific Study of the So-Called Psychical Processes in the Higher Animals, 1909
"The physiologist who succeeds in penetrating deeper and deeper into the digestive canal becomes convinced that it consists of a number of chemical laboratories equipped with various mechanical devices."
— from Nobel Lecture, 1904
All quotes by Ivan Pavlov (368)
The constant conditions of life produce constant habits.
The cerebral hemispheres are the organ of the animal's relations with the surrounding world.
The sound of a bell, the sight of a light, previously indifferent, now become signals for food and evoke a salivary secretion.
Gradualness, gradualness, and gradualness. From the very beginning of your work, school yourself to severe gradualness in the accumulation of knowledge.
Remember that science demands your whole life. And even if you had two lives to give, they would not be enough.
The digestive canal is a tube passing through the entire organism and communicating with the external world.
The organism is a machine which regulates itself.
The aim of reflexology is to study all the reflexes which can be established in the organism.
The salivary glands are a mirror of the cerebral hemispheres.
The physiologist must consider the organism as a whole, in its relations with the surrounding medium.
The conditioned reflex is a universal physiological phenomenon in the animal world, and in ourselves as well.
The activity of the cerebral hemispheres is based on the principle of the temporary connection.
The physiologist who would remain a physiologist must go on to the study of the highest nervous activity.
Do not be misled by the apparent simplicity of the conditioned reflex method. It requires the greatest attention and precision.
The higher nervous activity is a function of the cerebral cortex.
The animal is a system, a complex of innumerable reactions to external influences.
The physiologist must be a materialist in his method, but he need not be a materialist in his philosophy.
The study of conditioned reflexes has thrown a bright light on the mechanism of the most complex relations of the animal to the external world.
The first duty of the physiologist is to establish the facts, and only then to philosophize about them.
The conditioned reflex is a precise, objective, and measurable phenomenon.
