Effect of a Constant Magnetic Field on Invertebrate Neurons

  • D. R. Russell

Abstract

Investigations of possible effects of magnetic fields on neurons have been carried out with varied degrees of systematic experimentation and success. McKendrick(1) in studying the effects of a magnetic field on the sciatic nerve of a frog indicated that the magnetic field reduced the irritability of the nerve-muscle preparation. The results of his experiments were not conclusive. Erdman(2) conducted experiments which indicated that magnetic fields (greater than 1000 Oe) initially decreased, and then increased, the chronaxie of the frog sciatic nerve-muscle preparation. Liberman et a1.,(3) in an attempt to verify Erdman’s results, concluded that a 10,000-Oe magnetic field did not affect single fibers of the sciatic nerve. Young and Gofman(4) observed that the isolated frog vagal heart preparation exhibited a decrease in the duration of vagal inhibition, work per cycle, contractility, and a high frequency of irregularity after cessation of magnetic fields of 4,000–15,000 Oe.
