[Dynamics of the latent periods of the avoidance response and its correlation with adaptive behavior in the rat].
In the chamber with one-way avoidance, the latency of avoidance reaction was repeatedly evaluated every 30 s. Chronograms revealed clear minute latencies fluctuations. Some rats had a short (1-2.5 min) biorhythm period, others--a much longer one (10 min and more). The structure of rhythmic oscillations correlated with the ability of animals to relearning in the Y-maze. At slow oscillation process, the relearning was more difficult. d,l-amphetamine in a dose eliciting stereotype movements, impeded the relearning, and this coincided with prevailing of slow waves on chronograms.
