Working at the systems level of analysis, we will use the term functional architecture to concern what processing components exist, how they are interconnected, and what information-processing functions each is involved in. In this paper, experimental evidence for the primate neocortex is analysed for conclusions concerning the existence of neural areas, for corticocortical connectivity among neural areas, and for the involvement of each cortical neural area in the functioning of the brain. We characterize the information-processing function for each neural area in terms of the types of information it is associated with, and conceive of its activity as processing, storage and transmission of data of the corresponding types for that area. We also adapt concepts of goal, plan, sequence, event and context for the description of information processing in the neocortex. This analysis shows that the primate neocortex consists in the main of a perception hierarchy, an action hierarchy and connections between them. In other words, from an information-processing point of view, the primate neocortex has a hierarchical perception-action architecture.
在系统层面的分析中，我们将使用“功能架构”一词来关注存在哪些处理组件、它们如何相互连接以及每个组件参与哪些信息处理功能。在本文中，我们分析了灵长类动物新皮层的实验证据，以得出关于神经区域的存在、神经区域之间的皮质-皮质连接以及每个皮质神经区域在大脑功能中的参与情况的结论。我们根据每个神经区域所关联的信息类型来描述其信息处理功能，并将其活动设想为对该区域相应类型数据的处理、存储和传输。我们还采用目标、计划、序列、事件和上下文等概念来描述新皮层中的信息处理。该分析表明，灵长类动物新皮层主要由一个感知层次结构、一个动作层次结构以及它们之间的连接组成。换句话说，从信息处理的角度来看，灵长类动物新皮层具有层次化的感知-动作架构。
