[Nonlinear behavior of nerve fibers with constant current stimulation]

There are abundant nonlinear phenomenons in life systems. Using the Hodgkin-Huxley model, we studied the excitability of single nerve fiber under constant current stimulation by means of computer simulation. It was found that stimulated with different current intensities, the membrane potentials of the nerve fiber are at equilibrium points or periodic oscillations. And the frequencies of the periodic oscillations are obtained.
