Abstract

Manifestation of typological characteristics of higher nervous activity in EEG energo-(amplitude-) frequency parameters were studied in chronic experiments on cats in a state of rest. EEG Of the animals of a strong nervous system type were characterized by a comparatively steady prevalence of alpha-activity and a stable relationship between the summary energy parameters of the basic frequencies. The brain electrical activity of cats with a weak type of higher nervous activity was in some cases characterized by instability of the general pattern: the summary parameter of each rhythm often changed, while at different intervals of time any of them could be recorded as predominant; in other cases slow waves were steadily prominent, and the summary energy of alpha-activity was low.
