Magnetic Stimulation of Peripheral Axons: Models and Experiments

  • Peter J. Basser


Although clinical magnetic stimulation was demonstrated a decade ago [1, 2, 3], little work has been done since then to elucidate the underlying physical principles that govern nerve excitation by electromagnetic fields [4]. The potential benefits of this understanding are numerous. A mathematical model of magnetic stimulation could be used to design improved hardware (e.g., coils and current sources) and to provide the expressions with which to perform this optimization. A model would also permit us to design experiments to test its own predictions, to reconcile observations in numerous descriptive experiments, and to suggest unanticipated sources of experimental error. It could also be used to predict the site of stimulation along an axon and to derive clinically useful scaling laws.
