| Abstract(in English) | The associative memory model is one of typical neural network model and has equilibrium state called spurious state in which memory patterns can't be recalled. It is because the associative memory model has many equilibrium states besides memory patterns. In recent studies, synaptic depression, which is a kind of short-term synaptic plasticity, makes memory state instable and causes switching phenomena among memories. In this study, we find that the synaptic depression destabilizes spurious state and induces an oscillation of network. We find out that the oscillation is explained as two-dimensional circular motion by using principal component analysis. |
