Abstract
Chaotic Resonance (CR) is known as a phenomenon like Stochastic Resonance (SR) without stochastic noise. SR in which the presence of noise helps a nonlinear system in amplifying a weak (under barrier) signal has been observed in neural systems. However CR has scarcely been examined in the neural systems and recently the concern with the responses in CR in neural systems has been growing. In this paper, we evaluate the signal response in CR in the promising Izhikevich neuron model and its assembly. It is confirmed that chaotic states in CR can respond to the weak signal which is not able to be sensed by periodic stable states.
