Heterogeneity-enhanced stochastic resonance improves liquid-state computing in delayed spiking neural networks
Sandipan Nath, Marius E. Yamakou
We investigate the joint effects of stochastic forcing and quenched structural heterogeneity on stochastic resonance (SR) and liquid-state computation in a small-world network of e…
Interaction order controls stochastic-resonance enhancement and redistribution in delayed multiplex neural networks
Alina Schlabritz, Marius E. Yamakou
We investigate stochastic resonance in a hierarchy of delayed excitable systems, from a single FitzHugh--Nagumo neuron to single-layer and duplex networks with autaptic, pairwise,…
Analysis of inverse stochastic resonance: Effects of neural excitability and timescale separation
Marius E. Yamakou, Torben Krüger, Hermann Schulz-Baldes
We analyze inverse stochastic resonance (ISR) in a bistable FitzHugh--Nagumo neuron driven by additive noise in the voltage variable, focusing on how neural excitability and timesc…
A Lyapunov stability proof and a port-Hamiltonian physics-informed neural network for chaotic synchronization in memristive neurons
Behnam Babaeian, Marius E. Yamakou
We study chaotic synchronization in a 5D Hindmarsh--Rose neuron model augmented with electromagnetic induction and a switchable memristive autapse. For two diffusively coupled iden…
Effect of diversity distribution symmetry on global oscillations of networks of excitable units
Stefano Scialla, Marco Patriarca, Els Heinsalu +2
We investigate the role of the degree of symmetry of the diversity distribution in shaping the collective dynamics of networks of coupled excitable units modeled by FitzHugh-Nagumo…
Reduced-order adaptive synchronization in a chaotic neural network with parameter mismatch: A dynamical system vs. machine learning approach
Jan Kobiolka, Marius E. Yamakou
In this paper, we address the reduced-order synchronization problem between two chaotic memristive Hindmarsh-Rose (HR) neurons of different orders using two distinct methods. The f…
Inverse stochastic resonance in adaptive small-world neural networks
Marius E. Yamakou, Jinjie Zhu, Erik A. Martens
Inverse stochastic resonance (ISR) is a phenomenon where noise reduces rather than increases the firing rate of a neuron, sometimes leading to complete quiescence. ISR was first ex…
Self-induced-stochastic-resonance breathing chimeras
Jinjie Zhu, Marius E. Yamakou
The study in [Phys. Rev. Lett. 117, 014102 (2016)] discovered a novel type of chimera state known as coherence-resonance chimera (CRC), which combines the effects of coherence reso…
Diversity-induced decoherence
Marius E. Yamakou, Els Heinsalu, Marco Patriarca +1
We analyze the effect of small-amplitude noise and heterogeneity in a network of coupled excitable oscillators with strong time scale separation. Using mean-field analysis, we unco…
Control of noise-induced coherent oscillations in three-neuron motifs
Florian Bönsel, Patrick Krauss, Claus Metzner +1
The phenomenon of self-induced stochastic resonance (SISR) requires a nontrivial scaling limit between the deterministic and the stochastic timescales of an excitable system, leadi…
Levy noise-induced self-induced stochastic resonance in a memristive neuron
Marius E. Yamakou, Tat Dat Tran
Self-induced stochastic resonance (SISR) is a subtle resonance mechanism requiring a nontrivial scaling limit between the stochastic and the deterministic timescales of an excitabl…
Chaotic Synchronization of memristive neurons: Lyapunov function versus Hamilton function
Marius E. Yamakou
We study the dynamical behaviors of this improved memristive neuron model by changing external harmonic current and the magnetic gain parameters. The model shows rich dynamics incl…
Control of coherence resonance by self-induced stochastic resonance in a multiplex neural network
Yamakou E. Marius, Juergen Jost
We consider a two-layer multiplex network of diffusively coupled FitzHugh-Nagumo (FHN) neurons in the excitable regime. It is shown, in contrast to SISR in a single isolated FHN ne…
