当呈现给双眼的刺激不一致并且不能融合在一起成为单个视觉感受时，观察到双眼竞争。在这种情况下，大脑感知到两个图像的交替，占主导地位的感知的平均持续时间为几秒钟。我们提出了一个计算模型的竞争与尖峰频率适应下颞叶皮层（IT），能够重现实验分布的优势相持续时间。我们还包括从IT到早期视觉区域（V4）的自上而下的连接，这些连接产生了观察到的这些区域中一些神经元的感知调制反应。(C)2002 Elsevier Science B.V.保留所有权利。
Binocular rivalry is observed when the stimuli presented to both eyes are incongruent and cannot be fused together into a single percept. In such a situation the brain perceives an alternation of the two images, with the mean duration of the dominant perception being a few seconds. We propose a computational model of competition with spiking frequency adaptation in the inferotemporal cortex (IT) that is able to reproduce the experimental distributions of the dominant phase durations. We also include top-down connections from IT to earlier visual areas (V4) that generate the observed perception-modulated response of some neurons in these areas. (C) 2002 Elsevier Science B.V.
