Natural systems are undeniably subject to random fluctuations, arising from either
environmental variability or thermal effects. The consideration of those fluctuations supposes …

We show that the correlation between the frequency of subthreshold pacemaker activity and
the response of an excitable array is resonantly dependent on the intensity of additive …

We study the phenomenon of spatial coherence resonance in a two-dimensional model of
excitable media with FitzHugh-Nagumo local dynamics. In particular, we show that there …

We study the spatial dynamics of spiral waves in noisy Hodgkin–Huxley neuronal
ensembles evoked by different information transmission delays and network topologies. In …

In this paper different topologies of populations of FitzHugh–Nagumo neurons have been
introduce to investigate the effect of high-frequency driving on the response of neuron …

Noise is an inherent part of neuronal dynamics, and thus of the brain. It can be observed in
neuronal activity at different spatiotemporal scales, including in neuronal membrane …

Spatial coherence resonance in a spatially extended system that is locally modeled by
Hodgkin–Huxley (HH) neurons is studied in this paper. We focus on the ability of additive …

We study the impact of additive Gaussian noise and weak periodic forcing on the dynamics
of a scale-free network of bistable overdamped oscillators. The periodic forcing is introduced …

We study effects of different network topologies on the noise-induced pattern formation in a
two-dimensional model of excitable media with FitzHugh–Nagumo local dynamics. In …

The response of three coupled FitzHugh–Nagumo neurons, under high-frequency driving, to
a subthreshold low-frequency signal is investigated. We show that an optimal amplitude of …
