Abstract
Using computer simulations, the authors have demonstrated that temporal compression based on theta phase coding in the hippocampus is essential for the encoding of episodic memory occurring on a behavioral timescale (> a few seconds). In this study, the memory of reading literature was evaluated using a network model based on theta phase coding. Input was derived from an eye movement sequence during reading and each fixated word was encoded by a vector computed from a statistical language model with a large text corpus. The results successfully demonstrated a memory generated by a word sequence during a 6-min reading session and this suggests a general role for theta phase coding in the formation of episodic memory.
