Conclusions
-
1.
The latent periods of the conditioned avoidance reaction in rats in the maze show rhythmic fluctuations with time. According to the nature of the wave process the animals could be divided into two groups: those with predominantly high-frequency and those with predominantly low-frequency fluctuations.
-
2.
The characteristics of the rhythmic fluctuations in the latent period of a simple conditioned response correlate with the capacity of animals for reeducation. Rats possessing high-frequency elements in the fluctuation curve more easily rearrange the path of the avoidance habit in the Y-maze than do animals in whom the low-frequency rhythm predominated.
-
3.
At a dose inducing stereotypy, amphetamine leads to deoptimization of behavior in the form of difficulties in retraining of rats in the Y-maze. This is accompanied by an increase in the slow-wave component in the dynamics of latency in the simple avoidance reaction.
