INFLUENCE OF INFRALOW-FREQUENCY MAGNETIC-FIELD ON THE NERVOUS CELLS RHYTHM AND THEIR TOLERANCE TO HYPOXIA

The direct effect of infralow-frequency (0,05, 0,1, 0,25 Hz, 100 nT) magnetic fields (MF) was demonstrated on the brain cellular-tissue model-surviving slices of mouse cerebellum. MF influence is a trigger for the nervous cells. MF-5 Hz revealed two-phases response: inhibition and excitation of the impulse activity of neurons. Besides that we recorded convulsive effect of MF. The experiments with simultaneous exposure of hypoxia and MF revealed a prohypoxia effect of MF, when the oxygen concentration was very low and also after reoxygenation. The surviving slices may be used as a model for studying the fine mechanisms of influence of different intensity MF on the nervous cells.
