Abstract

Chaotic resonance (CR) is a phenomenon similar to stochastic resonance (SR), but 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, there has been no fundamental study that investigates the signal responses of CR in the spiking ...
