  • Title: [Bioelectrical activity of the neuromuscular and sympathetic systems exposed to a constant magnetic field].
    Author: Klimovskaia LD, Krotova SB.
    Journal: Kosm Biol Aviakosm Med; 1979; 13(6):58-61. PubMed ID: 502428.
    Abstract:
    The experiments on an isolated frog neuromuscular preparation gave evidence that an exposure to stable magnetic fields of 1000-4000 Oe did not influence the time parameters, amplitude and pattern of the action potentials of the gastrocnemius muscle induced by ischiatic nerve stimulation with single impulses. Similar results were obtained from an analysis of electric responses of the upper cervical sympathetic mode to the stimulation of preganglionar fibers in in situ experiments on urethane anesthesized rabbits subjected to a total exposure of a stable magnetic field (500-3000 Oe). In addition, an exposure to a stable magnetic field of 4000 Oe brought about a decrease of the level of depression of the action potential of muscles after conditioning tetanus.
