Magnetic nerve stimulation has been widely used in neurophysiological research and clinical diagnosis. We have developed a technique for localized and vectorial magnetic stimulation using a figure-of-eight coil. Most previously reported magnetic stimulation techniques have been for single-pulse stimulation, using a magnetic coil driven by currents discharged from a capacitor bank. Our technique, in contrast, is for repetitive magnetic stimulation with train pulses. Using a figure-of-eight coil, we simulated the nerve excitation elicited by a train of pulsed magnetic stimulation. We used the parameters of the Frankenhaeuser-Huxley model. The results show that the threshold for nerve excitation is reduced by previous stimulation and that the refractory period is reduced by increasing the pulsed current flowing in a stimulating coil.
