Abstract
We propose a model for the lateral connectivity of orientation-selecti ve cells in the visual cortex. We study the properties of the input si gnal to the visual cortex and find new statistical structures that hav e not been processed in the retino-geniculate pathway. Using the idea that the system performs redundancy reduction of the incoming signals, we derive the lateral connectivity that will achieve this for a set o f orientation-selective local circuits, as well as the complete spatia l structure of a network composed of such circuits. We compare the res ults with various physiological measurements.
