[Structural changes in the central nervous system induced by a constant magnetic field].
The effect of the permanent magnetic field (PMF) on the brain cortex of rats has been assessed. The study was performed on neurons, astrocytes and synapses of post- and precentral brain cortical zones. CNS sensitivity to PMF was determined. When the animals were exposed to PMF once or 15 times the changes in microstructures were of compensatory-adaptive character, indicative of the enhancement in their functional activity. When the animals were exposed to PMF 30 times, dystrophic changes underlying the impairment of CNS functional activity developed, 10 days after the exposure to PMF was discontinued regenerative intracellular processes were revealed.
