Abstract

A digital spiking neuron is a wired system of shift registers that can mimic nonlinear dynamics of simplified spiking neuron models. In this paper, we present a novel pulse-coupled system of the digital spiking neurons. The coupled neurons can exhibit various pseudoperiodic synchronizations, non-periodic synchronizations, and related bifurcations. We derive theoretical parameter conditions that guarantee occurrence of typical synchronization phenomena. Also, the theoretical results are validated by numerical simulations.
