Abstract : A theory for neuron selectivity in visual cortes is presented and compared with neurophysiological data. In this theory, a neuron becomes maximally selective over the set of patterns presented to it. Theoretical predictions corespond well with results of various experimental paradigms including normal rearing, monocular and binocular deprivation, and reverse suture. Extensions of the theory to cortical networks based on anatomical data are discussed. The ideal synapse, which can alter its function between excitatory and inhibitory modes, must be resolved into excitatory and inhibitory synapses to agree with anatomical observation. A mathematical appendix provides stability analysis of the model's fixed point behavoir.
