The self-adaptive neuron circuit comprises an excitation pulse, a non-volatile memristor and a capacitor; a volatile memristor, the capacitor and the resistor form a discharge loop; voltage signals at the two ends of the resistor serve as output pulses of the neuron circuit. The working process is as follows: after the nonvolatile memristor receives an excitation pulse, the capacitor is charged through the charging loop, the voltage of the capacitor is gradually increased, when the voltage at the two ends of the volatile memristor is smaller than a threshold voltage, the output pulse is 0, and when the voltage at the two ends of the volatile memristor is larger than or equal to the threshold voltage, the capacitor is discharged through the discharging loop. Voltages at two ends of the resistor serve as output pulses to generate action potentials. Under the action of the excitation pulse, the resistance value of the nonvolatile memristor is gradually increased, so that the frequency of the generated action potential is gradually reduced, and the characteristic that neurons gradually adapt to constant external stimulation is simulated. According to the invention, the adaptive function of neurons is simulated.
