[Ontogenetic formation of the ability for endogenous account of time and its dependence upon the anxiety level in rats].
Rats' ability for endogenous account of short time intervals progresses along with maturation. In 3- and 6-month old animals, it parabolically depends upon the level of anxiety: there is an average optimum level of anxiety needed for precise and effective account of time. Deviations from this level decrease the biochronometrical ability. In addition, a time perception dependence on locomotive sphere and the state of sympathetic adrenal system's peripheral part, was revealed.
