More Information
Summary:A mathematical model was used to simulate magnetic stimulation on a mammalian myelinated axon. The capacitance and resistance of the stimulator and the coil geometry were utilized as parameters for optimizing the efficiency of magnetic stimulation. Results showed that the optimal coil design required the minimum inner radius and height, and therefore a pancake-like coil was more efficient for magnetic stimulation. Such an argument was valid for both the infinite and the semi-infinite axons. A stimulator with smaller resistance as well as capacitance was able to provide more efficient magnetic stimulation.
