Abstract
We study the synchronization phenomena in a pair of Hindmarsh-Rose (HR) neurons with chemical coupling. We find that excitatory synaptic coupling pushes two neurons towards antisynchrony, and weak or moderate inhibitory synaptic coupling pushes two neurons towards antisynchrony too, but sufficiently strong inhibitory synaptic coupling pushes two neurons towards synchronized periodic oscillations without spikes. And synchronization patterns can’t be changed even if the intrinsic frequency of individual cell is changed by modulating external input current. Investigating the effect of synapse on ISIs bifurcation structures shows that whether excitatory synapse or inhibitory synapse, both remarkably influence ISIs structures. That is, the chemical coupling between neurons wholly distorts the neuronal information.
