Nonlinear Dynamical Properties of Excitable Neurons

Under the Hodgkin-Huxley(H-H) model,and using numerical method,the nonlinear dynamical properties of excitable neurons are studied through changing of the parameters that stand for the excitability of neurons in the model.The result shows that the larger the parameters are,the higher becomes the threshold that the action potential taking place and the larger the range of stimulation that the neurons can bear.It also shows that there is a special parameter domain for each kind of neuron.When the parameter is changing within the domain,the response of neurons to a constant stimulation is chaotic.
