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 T0 the time to peak of the magnetic field
