Abstract

Theta phase precession is an interesting phenomenon in hippocampusand may enhance learning and memory. Based on Harris KD et al. and Magee JC’s electrophysiology experiments, a biology plausible spiking neuron model for theta phase precession was proposed. The model is both simple enough for constructing large scale network and realistic enough to match the biology context. The numerical results of our model were shown in this paper. The model can capture the main attributes of experimental result. The relationship of phase shift with place shift in experiment was well repeated in our model. An STDP network constructed with our model neurons can memorize place sequence after single time learning with high accuracy. Such a model can mimic the biological phenomenon of theta phase precession, and preserve the main physiology factors underline theta phase precession.
