[Effect of an electromagnetic field on conditioned reflex maintenance and the nucleic acid content of brain tissues during carotid artery constriction].
It has been discovered in chronic experiments on 54 rats that during ligation of the carotid artery, the action of the decimetric electromagnetic field (DMB-irradiation) produces in some cases the deterioration of the rats' status that manifests in paroxysms eventuating in lethal outcomes, whereas in other ones, makes the conditioned reflexes return to normal, accompanied by an increase in RNA content in the cortex of the large hemispheres. The mechanisms of an inconclusive action of DMB-irradiation is discussed as is the importance of changes in RNA content in the cortex for the mechanisms of a favourable action of irradiation on the recovery of brain function in circulatory disorders. The possibilities of using DMB-irradiation under the clinical conditions are also discussed.
