[Experimental neurosis in developing rats].

An experimental neurosis was obtained in thirty, young one-month rats. To reveal age peculiarities of neurotization by the suggested method 5 adult animals were tested. It is shown that 5-7 days were needed for the deterioration of neural processes in developing rats. The neurotization of adult animals required a longer period--up to 20 days. In young animals, the experimental neurosis was elicited and developed more rapidly, with more prominent pathological reactions. Heightened sensitivity to stimuli of moderate intensity, presented in a strict cyclic rhythm of high frequency was characteristic of one-month rats.
