We study the effects of the interplay between diversity and noise in a 3D network of FitzHugh-Nagumo elements, with topology and dimensions chosen to model a pancreatic β-cell cluster, as an example of an excitable cell network. Our results show that diversity and noise are non-equivalent sources of disorder that have different effects on the network dynamics: their synchronization mechanisms may act independently of one another or synergistically, depending on the mean value of the diversity…

Diversity-induced decoherence.

We analyze the effect of small-amplitude noise and heterogeneity in a network of coupled excitable oscillators with strong timescale separation. Using mean-field analysis, we uncover the mechanism of…

Hubs, diversity, and synchronization in FitzHugh-Nagumo oscillator networks: Resonance effects and biophysical implications.

A coupled oscillator network model with cubic lattice topology is developed, showing that the emergence of pacemakers or hubs in the system can be viewed as a natural consequence of oscillator population diversity.

Dynamic random links enhance diversity-induced coherence in strongly coupled neuronal systems

The results indicate that the largest coherence in the spike events emerge when the coupling strength is high, and when the underlying connections are mostly random and dynamically changing.

If the spatial correlation of the noise exceeds that of the network, the excitation patterns disappear in favor of cloudy structures, directly rendering the underlying spatial noise field.

Effects of clustering on diversity-induced resonance in hidden metric spaces.

The results imply that it is possible to control the response of spatially extended systems to external signals by the manipulation of network clustering, and the optimal diversity strength for maximum response is reduced.

Pattern competition as a driver of diversity-induced resonance

Diversity-induced resonance, the emergence of coherent spatiotemporal patterns at intermediate parameter disorder, is a well-known phenomenon in lattices of excitable elements. Here we study the…

Stochastic resonance in a globally coupled neuronal network

The phenomenon of stochastic resonance in a globally coupled neuronal network has been studied via numerical simulation. The ability of the network to detect weak (subthreshold) periodic signals can…

Multiple Spatial Coherence Resonances and Spatial Patterns in a Noise-Driven Heterogeneous Neuronal Network

Heterogeneity of the neurons and noise are inevitable in the real neuronal network. In this paper, Gaussian white noise induced spatial patterns including spiral waves and multiple spatial coherence…

Diversity-Induced Resonance in a System of Globally Coupled Linear oscillators

The purpose of this paper is to analyze in some detail the arguably simplest case of diversity-induced resonance: that of a system of globally-coupled linear oscillators subjected to a periodic…

Diversity-induced resonance.

Findings show that intrinsic diversity might have a constructive role and suggest that natural systems might profit from their diversity in order to optimize the response to an external stimulus.
