Excitation of frog sciatic nerve using pulsed magnetic fields effect of waveform variations

Abstract

We examined the relative effectiveness of overdamped and of (truncated) underdamped magnetic field pulses in exciting frog sciatic nerve. Waveforms were compared by finding the stimulus magnitude (Vh) corresponding to half-maximal tension developed in gastroenemius muscle. Vh varied inversely with T/sub 0/ the time to peak of the magnetic field.
