When the two eyes view discrepant monocular stimuli, stable single vision gives way to alternating periods of monocular dominance; this is the well-known but little understood phenomenon of binocular rivalry. This article develops a neural theory of binocular rivalry that treats the phenomenon as the default outcome when binocular correspondence cannot be established. The theory posits the existence of monocular and binocular neurons arrayed within a functional processing module, with monocular neurons playing a crucial role in signaling the stimulus conditions instigating rivalry and generating inhibitory signals to implement suppression. Suppression is conceived as a local process happening in parallel over the entire cortical representation of the binocular visual field. The strength of inhibition causing suppression is related to the size of the pool of monocular neurons innervated by the suppressed eye, and the duration of a suppression phase is attributed to the strength of excitation generated by the suppressed stimulus. The theory is compared with three other contemporary theories of binocular rivalry. The article closes with a discussion of some of the unresolved problems related to the theory.
当两只眼睛观看不一致的单眼刺激时，稳定的单眼视觉会让位于单眼优势的交替期；这就是著名但鲜为人理解的双眼竞争现象。本文提出了一种双眼竞争的神经理论，将该现象视为无法建立双眼对应时的默认结果。该理论假定在一个功能性处理模块内存在单眼和双眼神经元，单眼神经元在发出引发竞争的刺激条件信号以及产生抑制信号以实现抑制方面发挥着关键作用。抑制被设想为在双眼视野的整个皮层表征上并行发生的局部过程。导致抑制的抑制强度与被抑制眼支配的单眼神经元池的大小有关，而抑制阶段的持续时间归因于被抑制刺激产生的兴奋强度。该理论与其他三种当代双眼竞争理论进行了比较。文章最后讨论了与该理论相关的一些未解决问题。
