[The reorganization of the functional system of defensive behavior in the zoosocial environment in Wistar rats].
Formation of the functional system of the active avoidance behaviour, its relationship with other forms of defensive behaviour and their reorganization in zoo-social interaction were studied in Wistar rats. Experiments were carried out under conditions of individual training of active avoidance behaviour and in a group. During learning all the forms of defensive behaviour and motor activity were recorded. After completing individual training triads of rats were formed on the basis of factor analysis of learning parameters. Regular characteristics of the species-specific defensive behaviour and new behavioural act, which appeared after the transition from individual to group behaviour, were described by the results of comparative analysis of parameters of behavioural acts, which were constituents of the defensive behaviour in individual and zoo-social experiments, as well as analysis of intragroup relations. It was found out that in a defensive situation placing the animal into zoo-social environment resulted in a decrease of the proportion of the lastly acquired habit in the individual behavioural repertory and prevalence of the earlier forms of defensive behaviour. "Leaders" and "outsiders" were described, which significantly differed by the level of efficiency of active avoidance behaviour in a group. "The price" of efficiency of active avoidance was determined for these animals by the relationship of motor activity in "trials and errors" during learning the new habit. This parameter enables to predict behaviour of a rat in zoo-social environment.
