Abstract(in Japanese) (See Japanese page)
Abstract(in English) All proceeding models of self-organization of topographic mappings have been based on self-sustaining local excitation in nerve fields. The proposed a new model using nerve fields which allow excitatory traveling waves and showed the formation of topographic mapping in the model. We can understand this model, as well as previous models, from the viewpoint of phase-locking between excitation patterns in two nerve fields interacting through the connection. It is different from any previous models in that the formation of the mapping depends on the spatio-temporal structure of the excitation patterns on the presynaptic nerve field. By decreasing the width of excitation gradually, computer simulations have shown the model to be able to form almost complete topographic mapping from initial values made by uniformly distributed random numbers.
