摘　　要：将嗅觉神经系统刺激、响应的Winner Less Competition(WLC)模型应用到视觉通道的视网膜神经元网络的计算之中,研究视网膜神经元的电位发放特性。通过数值实验,发现视网膜神经元的电位发放与生理实验的结果相近,得出WLC模型能够用于视觉通道计算研究的结论,并分析了视网膜神经元网络中神经节神经元电位发放的ISI,讨论了该网络模型的动力学性质。The WinnerLess Competition（WLC） model of restrain system is applied to the calculation of neuron network of retina of visual channel to study the features of potential of retina neuron. According to the numerical experiment, it found that the calculation results of potential of retina neurons closed to the results of physiological experiment. Therefore,WLC model can be used for the research of the calculation of visual channel. Besides, ISI of retinal ganglion cells is analyzed and simply discussed dynamical feature of this network model.
