Abstract(in English) | It is known that synaptic depression controls a gain for presynaptic inputs. However, it remains unknown what are functional roles of this gain control. We propose a new hypothesis that one of the functional roles is to enlarge basins of attraction. To verify this hypothesis, we employ a binary discrete-time associative memory model which consists of excitatory and inhibitory neurons. Using an extended mean-field theory and computer simulations, we find that the basins of attraction are enlarged whereas the storage capacity does not change. |
