[The function of the counting of time as the basis for the individual adaptive activity of the nervous system]

Abstract

An important role of time factor in adaptive process of organisms is shown on the basis of great literary material. The time perception is a result of the interrelationship of the so-called "biological clock" and learning during the whole ontogenesis. The hypothetical mechanisms of time perception are discussed. In own experiments the authors revealed more distinct expressiveness of high-frequency components in electroencephalogram spectrum and less expressiveness of low-frequency components in subjects underestimating time intervals compared with subjects overestimating them. A conception on the role of individual characteristics of nervous system in time perception is developed.
