Abstract(in English) | Rodent hippocampal CA1 place cells are known as the cells which encode the location of moving rats by theta phase precession in their place fields. Recently, it has been reported that there is a distortion of time corresponding to the rat's location encoded by a phase of the theta rhythm. Itskov et al. statistically derived the time-offset curve (TOC) representing time-distortion as a function of the theta phase. In this study, we try to reproduce the TOC by using a neural oscillator model based on the phase reduction theory. Finally, we show that the TOC theoretically obtained with phase response curves of hippocampal CA1 pyramidal neurons gives qualitative agreement with the observed TOC. |
