Abstract : A two-eye visual environment is used in training a network of BCM 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. The visual environment we use is composed of natural images. We show that for the BCM rule a natural image environment with binocular cortical misalignment is sufficient for producting networks with orientation selective cells and ocular dominance columns. This work is an extension of our previous single cell model (Shouval et al., 1996).
