A generalized asynchronous digital spiking neuron: Theoretical analysis and compartmental model

The most generalized version of asynchronous sequential logic circuit based neuron models is introduced, where the dynamics of the model is modeled by an asynchronous cellular automaton. In this paper, a new theoretical analysis method is presented, and stabilities of neuron-like orbits and occurrence mechanisms of relational neuron-like bifurcations are clarified theoretically. A synapse unit and a simple compartmental model are also presented, and their functions are confirmed numerically.
