Popis: Many experimental results suggest that more precise spike timing is significant in neural information processing. From this point of view, we construct a self-organizing model using the spatio-temporal patterns, where Spike-Timing Dependent Plasticity (STDP) tunes the conduction delays between neurons. STDP forms smoother map with the spatially random and dispersed patterns, whereas it causes spatially distributed and clustered firings for spatially continuous and synchronous inputs. These results suggest that STDP forms cell assemblies having a fine structure reflecting external stimuli.
