One of the roles of the hippocampus is viewed as modifying episodic memory so that it can contribute to form semantic memory. In this paper, we show that pattern completion ability of the hippocampal CA3 and symmetric spike timing-dependent synaptic plasticity (STDP) induce memory modification so that the hippocampal CA3 can memorize invariable parts of(More)
—In neural networks, when new patterns are learned by a network, the new information radically interferes with previously stored patterns. This drawback is called catastrophic forgetting or catastrophic interference. In this paper, we propose a biologically inspired neural network model which overcomes this problem. The proposed model consists of two(More)
