One of the role of the hippocampus is viewed as modifying episodic memory so that it can contribute to form semantic memory. In this paper, we show that the pattern completion ability of the hippocampal CA3 and symmetric spike timing-dependent synaptic plasticity induce memory modification so that the hippocampal CA3 can memorize invariable parts of repetitive episode as essential elements and forget variable parts of those as unnecessary ones.
