[The problem of participation of different brain regions in the reactions to the low-intensity magnetic and electromagnetic field exposure].

Abstract

Experimental analysis of the integral and pulsed bioelectric activity of the rabbit's various brain regions shows an ambiguous extent of their participation in the central nervous system reactions to low-intensity magnetic and electromagnetic fields with different parameters and conditions of exposure. This difference is determined not only by the location of brain structures in the head or by the field intensity, but, above all, by its functional state, which is reflected in the background. Artificial changes in the functioning of the original structures (administration of caffeine or adrenaline) altered the extent of their participation in the brain reaction, according to the drug action mechanism. The presence and severity of response depended on the structure and the biological significance of the impact, which is largely determined by the mode and conditions of exposure. Changing these parameters influenced the participation of the brain in its reaction in accordance with the adaptive response of the organism.

Main findings

Experimental analysis of rabbits' brain bioelectric activity indicated that different brain regions showed an ambiguous extent of participation in CNS reactions to low-intensity magnetic and electromagnetic fields under different exposure parameters and conditions. The extent of participation depended on the functional state reflected in baseline activity, and pharmacologic manipulation (caffeine or adrenaline) altered participation consistent with drug mechanisms; response presence/severity depended on exposure mode and conditions.
