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…
Optimal self-induced stochastic resonance in multiplex neural networks: electrical versus chemical synapses
Marius E. Yamakou, Poul G. Hjorth, Erik A. Martens
Electrical and chemical synapses shape the dynamics of neural networks and their functional roles in information processing have been a longstanding question in neurobiology. In th…
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…
Weak-noise-induced transitions with inhibition and modulation of neural oscillations
Marius E. Yamakou, Jürgen Jost
We analyze the effect of weak-noise-induced transitions on the dynamics of the FitzHugh-Nagumo neuron model in a bistable state consisting of a stable fixed point and a stable unfo…
