In order to simulate the nerve impulse waveform characteristic of the creature,a Riemann-Liouville fractional-order neural pulse oscillator was put forward in this paper,and it was used to simulate biologic neural signal.The computer simulation showed that it was a fractal dimension oscillator and it’s parameters can be adjusted according to the actual biologic neural signal, it’s output was not square wave or not rectangular wave,it can simulated shape characteristic of the actual biology neural signal such as neural pulse signal of the posterior cricoarytenoid muscle, action potential and so on by and large,it can provide technical support for neuronal function restoration in the future. These simulations indicated that the essence of the biology neural pulse was fractal dimension , not integral dimension.
