Abstract
Place information is coded by phases of the place cell firings within one theta cycle in the hippocampus (phase coding). In this study, a possible mechanism of the phase coding in the entorhinal cortex–hippocampus system is presented. The present entorhinal cortex layer II model generated a synchronized theta rhythm. A sequence of places was then coded in a theta cycle by entorhinal–hippocampal loop circuits with delay. The connections between place-related stellate cells were sequentially reinforced by sensory signals. After the learning session, the present entorhinal cortex–hippocampus model reproduced the phase precession.
