title: [Retention of a memory trace of learning induced by a new and extinctive stimulus in C57BL/6J and BALB/c mice].
abstract: Influence of preliminary habituation to the experimental box on passive avoidance learning was studied in mice of C57BL/6J and BALB/c strains. The 20-fold preexposure of mice to the environmental stimulus inhibited the acquisition and consequent retention of a memory trace in BALB/c mice and did not affect the acquisition in C57BL/6J mice. Subsequent retention in this strain was facilitated. The interstrain differences are discussed with respect to detected genetically determined types of behavior and exstinctive inhibition at the habituation stage.
