An Approach for Stabilizing Abnormal Neural Activity in ADHD Using Chaotic Resonance [PDF]
Frontiers in Computational Neuroscience, 2021 Reduced integrity of neural pathways from frontal to sensory cortices has been suggested as a potential neurobiological basis of attention-deficit hyperactivity disorder.

Chaotic Resonance in Typical Routes to Chaos in the Izhikevich Neuron Model [PDF]
Scientific Reports, 2017 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.

Recent Trends of Controlling Chaotic Resonance and Future Perspectives [PDF]
Frontiers in Applied Mathematics and Statistics, 2021 Stochastic resonance is a phenomenon in which the effects of additive noise strengthen the signal response against weak input signals in non-linear systems with a specific barrier or threshold.

Analysis of Chaotic Resonance in Izhikevich Neuron Model. [PDF]
PLoS ONE, 2015 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 without stochastic noise, which has been observed in neural systems.

Local random vector model for semiclassical fractal structure of chaotic resonance states [PDF]
Journal of Physics A: Mathematical and Theoretical, 2021 The semiclassical structure of resonance states of classically chaotic scattering systems with partial escape is investigated. We introduce a local randomization on phase space for the baker map with escape, which separates the smallest multifractal ...

Controlling Chaotic Resonance using External Feedback Signals in Neural Systems. [PDF]
Sci Rep, 2019 Stochastic resonance is a phenomenon in which the signal response of a non-linear system is enhanced by appropriate external noise. Likewise, a similar phenomenon can be caused by deterministic chaos; this is called chaotic resonance. Devices that employ

Leading Ruelle resonances of chaotic maps [PDF]
Physical Review E, 2000 The leading Ruelle resonances of typical chaotic maps, the perturbed cat map and the standard map, are calculated by variation. It is found that, excluding the resonance associated with the invariant density, the next subleading resonances are, approximately, the roots of the equation $z^4= $, where $ $ is a positive number which characterizes the ...

Resonance Eigenfunction Hypothesis for Chaotic Systems. [PDF]
Physical Review Letters, 2018 A hypothesis about the average phase-space distribution of resonance eigenfunctions in chaotic systems with escape through an opening is proposed. Eigenfunctions with decay rate γ are described by a classical measure that (i) is conditionally invariant ...

Semiclassical structure of chaotic resonance eigenfunctions. [PDF]
Physical Review Letters, 2006 We study the resonance (or Gamow) eigenstates of open chaotic systems in the semiclassical limit, distinguishing between left and right eigenstates of the nonunitary quantum propagator and also between short-lived and long-lived states.
