Abstract

Summary form only given. Layer 6 cells of the cortex have a massive feedback into layer 4, providing a strong inhibitory influence on the ascending excitatory inputs to the cortex and suggesting that layer may play a regulatory role by controlling the flow of input data into each critical area. In this context, the authors propose that the enlarged layer 4 that is characteristic of primary visual cortex in primates provides a shifting action which stabilizes the image data against retinal slip. A specific mechanism for producing these shifts is described, as well as a number of other adpative spatial-temporal filters that could also be implemented in this region.
