Islyamov R. Variability in response to the action of weak alternating magnetic field on rats with different individual characteristics

Response of animal organism to effect of alternating magnetic field demonstrates strong dependence on its individual-typological characteristics. Animals which have middle and high level of activity in the "open field" are characterized by motion of cerebral cortex upon the action of MF 8 Hz whereas animals with low activity are characterized by motion of thalamus and the hypothalamus. Similarly, the overall nature of changes which are caused by action of alternating magnetic field is such that there are initial leveling distinctions between different individual-typicalgroups. In the stereotypical reaction of the CNS on the influence of alternating magnetic field hemispheric asymmetry plays an important role and dominant role in the system response to the action of this factor belongs to the right hemisphere. In conditions of combined effect of alternating magnetic field and hypokinesia there is found potentiating effect of magnetic field for activity of monoamine oxidase which may be one of the causes of "stress-limiting" action of magnetic field on the level of integrative activity of the CNS. It is possible to consider probable multi-directional organism reaction which is associated with physiological and metabolic individuality in studies of weak factors in humans and animals organisms, especially in developing on health standards of maximum permissible background alternating magnetic field levels.
