双眼竞争是当两只眼睛看到不同场景时可能产生的交替感知。最近的心理物理学证据支持这样的观点，即双眼竞争的某些方面与其他双稳态感知具有功能相似性。我们基于以下假设（Logothetis & Schall，1989；Leopold & Logothetis，1996；Logothetis，Leopold，& Sheinberg，1996）构建了一个模型，即交替可以通过自上而下的皮质输入解释之间的竞争来生成，而不是通过输入之间的直接竞争来生成。最近的神经生理学证据表明，一些双眼神经元会随着感知的变化而受到调节。其他人则不然，即使他们在呈现给眼睛的刺激之间进行选择性。我们将模型扩展到层次结构来解决这些影响。
Binocular rivalry is the alternating percept that can result when the two eyes see different scenes. Recent psychophysical evidence supports the notion that some aspects of binocular rivalry bear functional similarities to other bistable percepts. We build a model based on the hypothesis (Logothetis & Schall, 1989; Leopold & Logothetis, 1996; Logothetis, Leopold, & Sheinberg, 1996) that alternation can be generated by competition between top-down cortical explanations for the inputs, rather than by direct competition between the inputs. Recent neurophysiological evidence shows that some binocular neurons are modulated with the changing percept; others are not, even if they are selective between the stimuli presented to the eyes. We extend our model to a hierarchy to address these effects.
