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.…
Long Term and Short Term Effects of Perturbations in a Immune Network Model
Rita Maria Zorzenon dos Santos, Mauro Copelli
In this paper we review the trajectory of a model proposed by Stauffer and Weisbuch in 1992 to describe the evolution of the immune repertoire and present new results about its dyn…
On the Aging Dynamics in an Immune Network Model
Mauro Copelli, Rita M. Zorzenon dos Santos, Daniel A. Stariolo
Recently we have used a cellular automata model which describes the dynamics of a multi-connected network to reproduce the refractory behavior and aging effects obtained in immuniz…
Physics of Psychophysics: Stevens and Weber-Fechner laws are transfer functions of excitable media
Mauro Copelli, Antonio C. Roque, Rodrigo F. Oliveira +1
Sensory arrays made of coupled excitable elements can improve both their input sensitivity and dynamic range due to collective non-linear wave properties. This mechanism is studied…
