Abstract
The structure of motor behavior in response to environmental tests, open field and with-a-partner situation, was studied in rats after 1, 3 and 6 wk of hypokinesia, as compared to the control. In control animals a relatively low level of orienting-investigation reactions and of grooming was observed and a low alimentary activity, which is considered as a manifestation of innate passive defensive reactions in the above situations. The disappearance of these reactions in the course of hypokinesia has 2 stages: predominant increase in orienting-investigating reactions (1-3 wk), and their subsequent decrease and an increase in the grooming (after 6 wk). The relation between innate and conditioned behavioral changes and the stability of alimentary behavior in rats was discussed.
