Bifurcations in synaptically coupled BVP neurons

We investigate bifurcations of periodic solutions in model equations of two and three Bonhoffer-van der Pol (BVP) neurons coupled through the characte ristics of synaptic transmissions with a time delay. Bifurcations of the co upled BVP neurons are compared with bifurcations of synaptically coupled Ho dgkin-Huxley neurons. We obtained a parameter set of the BVP system such th at the two systems are qualitatively very similar from a bifurcational poin t of view. This study is a base for the analysis of synaptically coupled ne urons with a large number of coupling strategies.
