INFLUENCE OF DIFFERENT MOTOR REGIMES MODULATING SPONTANEOUS ACTIVITY ON BEHAVIOR OF RATS

A method was developed of non-stressfull modulation of spontaneous mot or activity of rats. Restraint of mobility was found to inhibit sponta neous activity. Physiological stimulation of muscle activity by means of complication of food-procuring behaviour was accompanied by increas e of spontaneous activity. Physiological stimulation of motor activity was characterized by stability of orienting-exploratory behaviour, em otional reactivity, expression of <<freedom response>>, the best learn ing and working abilities of the animals. Regimes with imposing or res triction of muscle activity favoured the inhibition of spontaneous act ivity and the decrease of efficiency of adaptive behaviour. Motor regi mes accompanied by increase of spontaneous activity were found to be o ptimal for adaptive behaviour.
