title: [Extinction of passive avoidance response in various mouse strains].
abstract: Dependence of the passive avoidance extinction dynamics on a mouse strain was shown. Mice C57BL/6J and AKR/J extinguished more quickly relative to DBA/2J, CBA/Lac and BALB/c, and this extinction was stable. Individual instability of extinction was characteristic of C3H/HeJ mice. Extinction of the passive avoidance in mice CBA/Lac and BALB/c was slower: with a delay in the beginning and prolonged retention of memory trace of the shock exposure. In DBA/2J mice, the extinction was impaired. These data suggest that DBA/2J, CBA/Lac and BALB/c mice constitute groups of risk with high predisposition to impairment of extinction of memory of aversive events, which is thought to be a symptom of a depressive-like state.
