A two-eye visual environment, composed of natural images, is used in training a network of interacting BCM and Oja (PCA) neurons. This work is an extends our previous single cell model [10] to networks of interacting neurons. We study the effect of misalignment, between the synaptic density functions connecting both eyes to each single neuron, on the formation of orientation selectivity and ocular dominance. We show that for the BCM rule a natural image environment with binocular cortical misalignment is sufficient for producing networks of orientation selective cells with varying ocular dominance. Oja neurons in contrast are always perfectly binocular.
