[Ethological analysis of monkey behavior in biomedical research].

The importance of ethological analysis of primates behaviour during the medicobiologic research has been shown. The concrete examples of methods of differentiation and registration of behavioral patterns in the models of psychoemotional stress in primates are given. The systemic approach to the study of behaviour allows to determine the behavioral data of the individual state--the composition of functional spheres, the number of elements, the frequency of their appearance, the system of domination-subjection characteristics of the sequences of behavioral acts and to find out their dynamics in different stages of experiment. The comparison of these data with physiologicobiochemical data is necessary to obtain the integral picture of individual reaction to the experimental factors.
