title: [The effect of the duration of adaptation to laboratory conditions on the passive avoidance reflex in rats].
abstract: Influence of adaptation degree in new conditions on the passive avoidance was studied. The short period of habituation (3 days) positively influenced the rats' ability for memory trace retrieval. A negative correlation between the step through latency and anxiety in the elevated plus-maze, was shown. Prolongation of adaptation up to 9 days reduced levels of anxiety and retrieval of conditioned response. Modulating role of adaptation degree causing various anxiety levels in passive avoidance, is discussed.
