Different Types of Nervous System. Pathological States of the Cerebral Hemispheres as a Result of Functional Influences Exerted on Them36

WithIvan P. Pavlov

This chapter distinguishes four types: two “extreme” (excitable and inhibitory) and two “intermediate”, balanced types of nervous system. The classification of types was subsequently modified, since it did not completely correspond to the classification of temperaments proposed by Hippocrates by which Pavlov guided himself. The chapter also contains data on functional pathological states (“experimental neuroses”) produced by overstrain of the processes of excitation, inhibition, and their mobility.
