本文提出了一个关于灵长类视觉系统中早期视皮层潜在功能作用的模型。我们的假设是，早期的视觉区域，如V1，是重要的，在视觉加工过程中的各种高阶视觉区域之间的持续相互作用。这种相互作用是由高阶视觉区和V1之间的经常性连接介导的，表现在神经生理学实验中经常观察到的长潜伏期上下文敏感活动中，并且负责重新整合由高阶视觉区分析的信息。具体来说，我们考虑的情况下，整合“什么”和“在哪里”的信息，从腹侧和背侧流。我们发现，这样的皮层架构提供了简单的解决方案和新的见解注意路由和视觉搜索的问题。通过模拟一个大规模的神经动力学网络的计算能力，这种架构进行了测试。
This paper presents a model on the potential functional roles of the early visual cortex in the primate visual system. Our hypothesis is that early visual areas, such as V1, are important for continual interaction among various higher order visual areas during visual processing. The interaction is mediated by recurrent connections between higher order visual areas and V1, manifested in the long-latency context-sensitive activities often observed in neurophysiological experiments, and is responsible for the re-integration of information analysed by the higher visual areas. Specifically, we considered the case of integrating 'what' and 'where' information from the ventral and dorsal streams. We found that such a cortical architecture provides simple solutions and fresh insights into the problems of attentional routing and visual search. The computational viability of this architecture was tested by simulating a large-scale neural dynamical network.
