[Electrophysiological and neurochemical analysis of the biological effects of disturbances of Earth's magnetic field].
Geomagnetic effects on quantitative characteristics of alpha-rhythm were assessed by shifts in electroencephalograms recorded in 126 essentially healthy human subjects and changes in lipid metabolism in the cortex and white matter in 140 white rats. Indices of the geomagnetic activity were D, H and Z-components. The method of "epoch superposition" revealed an inconsistent alpha-rhythm depression and flattening out of the interhemispheric functional asymmetry against persistently high electrical activity in the right hemisphere, and biochemical asymmetry in consequence of different lipid transformation processes. Spotlighted were some nonspecific adaptive reactions to changes in the environment and stressful agents.
