视觉信息的皮层处理需要在编码视野中远处区域的神经元之间交换信息。有人认为，反馈连接是最好的候选人，这种快速的lng-stance互连。在整合模型中，从外侧膝状体核的大细胞层到达皮层的信息首先在顶叶皮层中发送和处理，顶叶皮层被视觉刺激非常迅速地激活。第一遍计算的结果通过反馈连接被发送回V1和V2区域，V1和V2区域作为视觉皮层其余区域的“活动黑板”：从顶叶皮层回注的信息用于指导下颞叶皮层中小细胞和koniocellular信息的进一步处理。(C)2001 Elsevier Science B. V.保留所有权利。
Cortical processing of visual information requires that information be exchanged between neurons coding for distant regions in the visual field. It is argued that feedback connections are the best candidates for such rapid lng-stance interconnections. In the integrated model, information arriving in the cortex from the magnocellular layers of the lateral geniculate nucleus is first sent and processed in the parietal cortex that is very rapidly activated by a visual stimulus. Results from this first-pass computation are then sent back by feedback connections to areas V1 and V2 that act as 'active black-boards' for the rest of the visual cortical areas: information retroinjected from the parietal cortex is used to guide further processing of parvocellular and koniocellular information in the inferotemporal cortex.
