ONTOGENIC FEATURES OF MOTOR EXPLORATORY R EACTION OF FEMALE LABORATORY MICE AFTER THE ACTION OF MALE URINE PHEROMONES

Motor exploratory activity of 36 and 41 days old female laboratory mic e CBA and C57BL/6 and their hybrides CBAB6F1 was studied after the act ion of urine of male mice CBA and CJ5BL/6. Five parameters were record ed, it was shown that formation of behavioural response to the sociall y important stimulus of pheromonal nature occured during puberty proce ss depending on the! donor and recipient genotypes and on the previous experience of interaction with the stimulus. The critical period of f ormation of this reaction was revealed in the ontogeny of females.
