The primate visual system contains dozens of distinct areas in the cerebral cortex and several major subcortical structures. These subdivisions are extensively interconnected in a distributed hierarchical network that contains several intertwined processing streams. A number of strategies are used for efficient information processing within this hierarchy. These include linear and nonlinear filtering, passage through information bottlenecks, and coordinated use of multiple types of information. In addition, dynamic regulation of information flow within and between visual areas may provide the computational flexibility needed for the visual system to perform a broad spectrum of tasks accurately and at high resolution.
灵长类动物的视觉系统在大脑皮层中包含数十个不同的区域以及几个主要的皮层下结构。这些细分区域在一个分布式层次网络中广泛互连，该网络包含几个相互交织的处理流。在这个层次结构中，使用了多种策略进行高效的信息处理。这些策略包括线性和非线性滤波、通过信息瓶颈以及协调使用多种类型的信息。此外，视觉区域内和之间信息流的动态调节可能提供视觉系统准确且高分辨率地执行广泛任务所需的计算灵活性。
