Some Problems of the Physiology of the Cerebral Hemispheres42

WithIvan P. Pavlov

This chapter considers the Croon Lecture delivered by Pavlov to the London Royal Society, May 10, 1928. Temperament is the most general characteristic of each individual person, as also each animal, the basic characteristic of the nervous system which lends a definite colouring to the entire activity of each individual. Considering that the subcortical centres closest to the hemispheres are centres of the special most complex unconditioned reflexes—food, active- and passive-defensive and others—and that their activity constitutes the physiological basis of the elementary emotions, the aggregate of vital functions will be determined by the character of the cerebral cortex which sends downward mainly excitation and inhibition, or both in their due balance.
