高斯白噪声对神经元映射模型随机共振的影响

摘要

通过数值模拟方法，在输入信号背景下研究了噪声诱导的神经元随机共振现象。基于二维映射神经元模型，利用高斯白噪声模拟了生物系统中的环境噪声，计算发现噪声能诱导神经元产生动作电位，随后在输入信号背景下，发现了噪声诱导的多重随机共振现象。%The phenomenon of stochastic resonance on neurons induced by noise was investigated by nu‐merical simulation in existing input signal .Based on the two‐dimensional map‐based neural model ,it was found that adding the noise led to induce spikes ,where Gaussian white noise was used to imitate the noisy environments of biological neural systems .Moreover ,it was also found that adding the noise led to multiple stochastic resonance in existing input signal .
