Abstract :
The study of the excitation properties of electrically stimulated nerve fibers has an important significance in many research fields, such as neural science, rehabilitation engineering, etc. It is important to study the electrical field distribution arising from electrical stimulation. In previous work, this study was simplified by ignoring some nonlinear factors and was done using an infinite and homogeneous volume conductor model. In this paper, an analytic solution method of electrical field distribution arising from electrical stimulation is proposed, in which some nonlinear factors, such as connective tissue, anisotropy of nerve fibers, etc., are considered. The solution results of two electrode configurations, intrafascicular point electrode and extraneural ring electrode, are given. Based on the solution, a system for simulating electrical stimulated nerve fiber excitation properties is built combining the membrane dynamic model of mammalian nerve fiber. This work makes it possible to study electrical stimulated nerve fiber excitation properties closer to actual cases
