Chaotic Resonance in Typical Routes to Chaos in the Izhikevich Neuron Model

Abstract Chaotic resonance (CR), in which a system responds to a weak signal through the effects of chaotic activities, is a known function of chaos in neural systems. The current belief suggests that chaotic states are induced by different routes to chaos in spiking neural systems. However, few stu...
