Abstract:: Abstract: In order to provide theoretical support for the bionic prototype circuit design of neurons and break through the constraints of traditional protection methods, the typical Hodgkin-Huxley model is used to carry out mathematical modeling and simulation on neurons. The time-domain response characteristics of nerve action potential stimulated by square wave signal are studied, and the effects of amplitude, period, duty cycle and stimulation duration of square wave signals on action potential are analyzed. The simulation results show that under the physiological parameters (electric conduction, capacitance, back electromotive force, etc) of neurons, 10 ms period and 6% duty cycle, the first and second sensitive parameters of the amplitude of square wave signal are 4 μA/cm2 and 21 μA/cm2, respectively, and that the thresholds of period and duty cycle are 8 ms and 6%, respectively. It is also found that the duration of signal stimulation is also an important factor to determine the action potential release.
