Analysis of chaotic resonance in Izhikevich neuron model

S Nobukawa, H Nishimura, T Yamanishi, JQ Liu - PloS one, 2015 - journals.plos.org
In stochastic resonance (SR), the presence of noise helps a nonlinear system amplify a
weak (sub-threshold) signal. Chaotic resonance (CR) is a phenomenon similar to SR but …

Chaotic resonance in typical routes to chaos in the Izhikevich neuron model

S Nobukawa, H Nishimura, T Yamanishi - Scientific reports, 2017 - nature.com
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 …

Multistability of gaits, the basin of attraction and its external topology in the simplest passive walking model on stairs

XB Rao, JS Gao, SL Ding, J Liang, J Zhang - Chaos, Solitons & Fractals, 2023 - Elsevier
