Anatomical and physiological evidence shows that the primate visual brain consists of many distributed processing systems, acting in parallel. Psychophysical studies show that the activity in each of the parallel systems reaches its perceptual end-point at a different time, thus leading to a perceptual asynchrony in vision. This, together with clinical and human imaging evidence, suggests strongly that the processing systems are also perceptual systems and that the different processing-perceptual systems can act more or less autonomously. Moreover, activity in each can have a conscious correlate without necessarily involving activity in other visual systems. This leads us to conclude not only that visual consciousness is itself modular, reflecting the basic modular organization of the visual brain, but that the binding of cellular activity in the processing-perceptual systems is more properly thought of as a binding of the consciousnesses generated by each of them. It is this binding that gives us our integrated image of the visual world.
解剖学和生理学证据表明，灵长类动物的视觉脑由许多并行运作的分布式处理系统组成。心理物理学研究表明，每个并行系统中的活动在不同时间达到其感知终点，从而导致视觉中的感知异步。这一点，再加上临床和人体成像证据，有力地表明这些处理系统也是感知系统，并且不同的处理-感知系统可以或多或少地自主运作。此外，每个系统中的活动都可以有与之相关的意识，而不一定涉及其他视觉系统的活动。这使我们不仅得出视觉意识本身是模块化的结论，反映了视觉脑的基本模块化组织，而且得出处理-感知系统中细胞活动的绑定更确切地应被视为由它们各自产生的意识的绑定。正是这种绑定赋予了我们视觉世界的完整图像。
