Simplified models of the lateral geniculate nucles (LGN) and stri(cid:173) ate cortex illustrate the possibility that feedback to the LG N may be used for robust, low-level pattern analysis. The information fed back to the LG N is rebroadcast to cortex using the LG N 's full fan-out, so the cortex-LGN-cortex pathway mediates extensive cortico-cortical communication while keeping the number of neces(cid:173) sary connections small.
