| Abstract(in English) | The cerebral memory system can recall different information from the same input stimulus depending on the context, and neuronal activity reflecting this process is observed in the monkey inferior temporal cortex. If we try to implement such context-dependent association by an artificial neural network, however, a serious computational difficulty caused by many-to-many correspondence between the contexts and the targets to be recalled. In the present paper, using a method of desensitizing some of cells according to the context to resolve this difficulty, we construct a neural network model performing a context-dependent memory task. The model not only reproduces the empirical data well but also gives a clear account for a phenomenon that has not been explicable. This strongly suggests that the brain is based on the same principle as the model, namely selective desensitization, for implementing context-dependent association. |
