Self-organization of orientation maps due to external stimuli in the primary visual area of the cerebral cortex is studied in a two-layered neural network which consists of formal neuron models with a sigmoidal output function. A cluster learning rule is proposed as an extended Hebbian learning rule
In our contribution we demonstrate, that orientation (OR) and ocular dominance (OD) cannot develop simultaneously in linear correlation-based learning (CBL) models, because OR and OD occupy separate domains in parameter space. We then analyse the conditions under which waves of spontaneous activity
