Deterministic excitable media under Poisson drive: power law responses, spiral waves and dynamic range
Tiago L. Ribeiro, Mauro Copelli
When each site of a spatially extended excitable medium is independently driven by a Poisson stimulus with rate h, the interplay between creation and annihilation of excitable wave…
Dynamic range of hypercubic stochastic excitable media
Vladimir R. V. Assis, Mauro Copelli
We study the response properties of d-dimensional hypercubic excitable networks to a stochastic stimulus. Each site, modelled either by a three-state stochastic susceptible-infecte…
Excitable Scale Free Networks
Mauro Copelli, Paulo R. A. Campos
When a simple excitable system is continuously stimulated by a Poissonian external source, the response function (mean activity versus stimulus rate) generally shows a linear satur…
Stability diagrams for bursting neurons modeled by three-variable maps
M. Copelli, M. H. R. Tragtenberg, O. Kinouchi
We study a simple map as a minimal model of excitable cells. The map has two fast variables which mimic the behavior of class I neurons, undergoing a sub-critical Hopf bifurcation.…
