We studied modifications of motor asymmetry in rats with different motor lateralization (dextrals, sinistrals, and ambidextrals) induced by low-intensity extra high-frequency (EHF) electromagnetic radiation (EMR), hypokinetic stress, and their combination. It was found that the development of hypokinetic stress in rats induced by limitation of their mobility results in a considerable decrease of the coefficient of motor asymmetry (up to inversion of its sign); this can be related to a decrease in the resistivity to stressing and adaptability of the organism to the influence of external factors. The influence of EHF EMR on the animals under conditions of both normal and limited motor activity resulted in an increase in the index of motor lateralization in animals of all phenotypic groups under study; probably, this helped to increase the adaptive capabilities of the organism.
