灵长类动物的视觉大脑由许多独立的、功能专门化的处理系统组成，每个处理系统都由几个明显有层次的阶段或节点组成。这里回顾的证据让我推测：(A)处理系统相对于彼此是自主的，(B)每个节点的活动在不同的时间到达感知终点，导致视觉上的感知不同步，以及(C)因此，每个节点的活动产生微意识。因此，视觉意识分布在空间和时间上，抽象的普遍组织原则在每个处理系统中分别应用。空间和时间分布的微观意识的结果是，它们的整合是一个多阶段的、无等级的过程，可能涉及到神经“胶水”。
The primate visual brain consists of many separate, functionally specialized processing systems, each consisting of several apparently hierarchical stages or nodes. The evidence reviewed here leads me to speculate (a) that the processing systems are autonomous with respect to one another, (b) that activity at each node reaches a perceptual end point at a different time, resulting in a perceptual asynchrony in vision, and (c) that, consequently, activity at each node generates a microconsciousness. Visual consciousness is therefore distributed in space and time, with the universal organizing principle of abstraction applied separately within each processing system. The consequence of spatially and temporally distributed microconsciousnesses is that their integration is a multistage, nonhierarchical process that may involve a neural "glue."
