我们提出了一个生物学上合理的模型，由霍奇金-赫胥黎型神经元网络的双眼竞争。我们的模型解释了实验和心理学观察到的现象：（1）它再现了在人类和灵长类动物中观察到的优势持续时间的分布，（2）它表现出连续优势持续时间的长度之间缺乏相关性，（3）对一只眼睛的刺激强度的变化只影响对侧眼睛的平均优势持续时间，而不影响同侧眼睛的平均优势持续时间，（4）平行增加两种刺激强度会降低平均优势持续时间。我们还推导出一个减少人口率模型，从我们的尖峰模型的显性持续时间对输入强度的依赖的显式表达式解析计算。我们还使用这个简化的模型来推导出一个表达式内看到的一个人的优势持续时间的分布。
We present a biologically plausible model of binocular rivalry consisting of a network of Hodgkin-Huxley type neurons. Our model accounts for the experimentally and psychophysically observed phenomena: (1) it reproduces the distribution of dominance durations seen in both humans and primates, (2) it exhibits a lack of correlation between lengths of successive dominance durations, (3) variation of stimulus strength to one eye influences only the mean dominance duration of the contralateral eye, not the mean dominance duration of the ipsilateral eye, (4) increasing both stimuli strengths in parallel decreases the mean dominance durations. We have also derived a reduced population rate model from our spiking model from which explicit expressions for the dependence of the dominance durations on input strengths are analytically calculated. We also use this reduced model to derive an expression for the distribution of dominance durations seen within an individual.
