Estimation of the Motor Threshold for Near-Rectangular Stimuli Using the Hodgkin–Huxley Model

Figure 1

FEM simulation of E-field norm distributions for different distances from the coil surface. (a) Placing figure-8 coil on the skull and the generated E-field. (b) E-filed 5 mm under the coil surface. (c) E-filed 10 mm under the coil surface. (d) E-field 15 mm under the coil surface. For this model, a 70 mm figure-8 coil is connected to 1 kV. The E-field norm means the amplitude of the electric field ().
