大脑皮层中信息流的主要途径是从皮层的中间层到上层和下层。然而，猫初级视觉皮层的上层可以在中间层的活动中断时直接由次级视觉皮层的输入驱动。上层活动既可以由中间层驱动，也可以由皮质-皮质直接输入驱动。这一结果的一个后果是，被认为进行低阶分析的皮层区域可能能够从高阶区域提取相当多的信息。
The main route of information flow in the cerebral cortex is from the middle layers of cortex to upper and lower layers. However, upper layers of the cat primary visual cortex can be directly driven by inputs from secondary visual cortex when activity in middle layers is disrupted. Upper-layer activity can be driven either by middle layers or by direct corticocortical inputs. One consequence of this result is that areas of cortex thought to be carrying out low-order analysis may be able to extract considerable information from higher order areas.
