| Abstract(in English) | In the present study, we propose a neural network model that generates the sparse and local excitation. Our model is based on two types of models. One is the neural network model that has Mexican-hat type interaction, and the other is the associative memory model. Our model generates the local excitation as is the case with the Mexican-hat-type network model, and can store a number of memory patterns on the local excitation as is the case with the associative memory model. The property of the system varies according to the firing rate of memory pattern in the associative memory model. We analyze the nature of our model for the case of various firing rates of the memory patterns. The analytical result shows that the sparse and local excitation in the proposed model can store a number of memory patterns only if the firing rate of the local excitation is equal to or lower than 50%. |
