Memory of Reading Literature in a Hippocampal Network Model Based on Theta Phase Coding
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.
