Transcranial Magnetic Stimulation: Modeling, Calculating and System Design

This paper summarized the basic principle of magnetic stimulation, and established the connection between action potential of neural cell and electrical parameters by simulating the neural model. The simulation of coil electromagnetic field and calculation of circuit mathematical model were also combined to derive out the electrical parameters. They are charging voltage, discharging current, stimulating waveform, which were required by magnetic stimulation. In the end, the optimized design and circuit of magnetic stimulation system were suggested, and simple parameter simulation of the model machine was carried out.
