Nearly all brain functions involve routing neural activity among a distributed network of areas. Understanding this routing requires more than a description of interareal anatomical connectivity: it requires understanding what controls the flow of signals through interareal circuitry and how this communication might be modulated to allow flexible behavior. Here we review proposals of how communication, particularly between visual cortical areas, is instantiated and modulated, highlighting recent work that offers new perspectives. We suggest transitioning from a focus on assessing changes in the strength of interareal interactions, as often seen in studies of interareal communication, to a broader consideration of how different signaling schemes might contribute to computation. To this end, we discuss a set of features that might be desirable for a communication scheme.

皮质皮质通信原则：提议的方案和设计考虑

几乎所有的大脑功能都涉及在分布式区域网络之间路由神经活动。理解这种路由不仅仅需要对区域间解剖学连接的描述：它需要了解是什么控制了通过区域间电路的信号流，以及如何调制这种通信以允许灵活的行为。在这里，我们回顾了有关如何实例化和调制通信（尤其是视觉皮层区域之间的通信）的建议，重点介绍了提供新视角的近期工作。我们建议从专注于评估区域间交互强度的变化（如区域间通信研究中经常看到的）转变为更广泛地考虑不同的信号方案如何有助于计算。为此，
