Features of the behavioral reactions of rats during exposure to constant electrical fields of varied intensities.

The dynamics of the spontaneous orienting-motoric activity and the character of the formation and of the extinction of conditioned reflex reactions during food and painful reinforcement in rats following exposure to a constant electrical field (CEF) with an intensity of from 30 to 160 kV/m were studied. It was established that as the result of the exposure to a CEF of relatively low intensity, orienting activity intensifies, and the formation and the extinction of the conditioned avoidance reaction slow down. In the presence of the effect of a CEF of medium intensity, an increase in activity in the vertical plane correlates with the rapid formation of the defense reflex and the prolonged maintenance of the conditioned reactions developed. In the presence of a high-intensity field the number of both horizontal and vertical locomotions decreases due to an increase in the proportion of static elements and grooming. The rate of formation of the conditioned reflexes with food and painful reinforcement slows sharply.

Simple and complex forms of behaviour, gas composition and acid-alkaline blood status in rats following exposure to the electro-static field (ESF) and iraionization, as well as in their offspring were studied. It has been found out, that ESF combined with the negative polarity air ionization damage motor and sex activity, conditioned-reflectory activity, changes blood indices. The observed disturbances in the organism of parent animals influenced fetus development.

Spontaneous motor orientation, the character of trained reflex responses to food and pain were studied in rats exposed to constant electrical fields (30-160 kV/m, 4 hrs daily for 30 days). A deceleration of responses, abolition of reflex extinction processes, decrease in the level of locomotor and orientation activity occurred along with increasing voltage. The system of negative emotional response seems to be most sensitive to CEF.
