Influence of Weakened Constant Magnetic Field on Nerve Cell Excitability

摘要

Attenuation of the constant magnetic field by a factor of 200-250 (to -0.2 uT) raised the excitation threshold and decreased the amplitude of the action potentials in the isolated frog sciatic nerve, and altered the conformation of carotenoids in the plasma membrane (sciatic axolemma) as well as in intracellular vesicles (cytosomes of snail ganglia) The variation in nerve excitability was supposedly caused by changes in the ordering of membrane lipids.
