Double coherence resonance in neuron models driven by discrete correlated noise
Thomas Kreuz, Stefano Luccioli, Alessandro Torcini
We study the influence of correlations among discrete stochastic excitatory or inhibitory inputs on the response of the FitzHugh-Nagumo neuron model. For any level of correlation t…
Coherent response of the Hodgkin-Huxley neuron in the high-input regime
Alessandro Torcini, Stefano Luccioli, Thomas Kreuz
We analyze the response of the Hodgkin-Huxley neuron to a large number of uncorrelated stochastic inhibitory and excitatory post-synaptic spike trains. In order to clarify the vari…
Desynchronized stable states in diluted neural networks
Ruediger Zillmer, Roberto Livi, Antonio Politi +1
The dynamical properties of a diluted fully-inhibitory network of pulse-coupled neurons are investigated. Depending on the coupling strength, two different phases can be observed.…
Low frequency fluctuations in a Vertical Cavity Lasers: experiments versus Lang-Kobayashi dynamics
Alessandro Torcini, Stephane Barland, Giovanni Giacomelli +1
The limits of applicability of the Lang-Kobayashi (LK) model for a semiconductor laser with optical feedback are analyzed. The model equations, equipped with realistic values of th…
Synchronization of extended chaotic systems with long-range interactions: an analogy to Levy-flight spreading of epidemics
Claudio Juan Tessone, Massimo Cencini, Alessandro Torcini
Spatially extended chaotic systems with power-law decaying interactions are considered. Two coupled replicas of such systems synchronize to a common spatio-temporal chaotic state a…
Contact processes with long-range interactions
F. Ginelli, H. Hinrichsen, R. Livi +2
A class of non-local contact processes is introduced and studied using mean-field approximation and numerical simulations. In these processes particles are created at a rate which…
