title: Effect of 1.5 T steady magnetic field on neuroconduction of a bullfrog sciatic nerve in a partially active state within several hours after extraction.
abstract: The bullfrog sciatic nerve within six hours after extraction was determined from the change with time in the action potential and the impedance to be a partially active nerve. Steady magnetic fields have been determined to be ineffective in the neuroconduction in the fresh nerve just after extraction. Although ion motions involved in the neuroconduction in the partially active nerve are not normal, it was confirmed that a 1.5 T steady magnetic field is ineffective in the neuroconduction in the partially active nerve. The obtained results suggest that the neuroconduction in damaged nerves is not affected by the 1.5 T steady magnetic field used in MRI.
