Spontaneous Replay of Temporally Compressed Sequences by a Hippocampal Network Model

  • D. A. August

Abstract

Recent experimental evidence suggests that the hippocampus replays a temporally compressed version of recently-learned spatial sequence information during slow-wave sleep. This phase of sleep is characterized by intermittent episodes of high-frequency firing known as sharp waves. Here we partially characterize a simplified neural network model of hippocampal area CA3, based on integrate-and-fire cells, which is capable of recalling temporally compressed sequence information during brief periods of high activity.
