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.…
Persistence solves Fermi Paradox but challenges SETI projects
Osame Kinouchi
Persistence phenomena in colonization processes could explain the negative results of SETI search preserving the possibility of a galactic civilization. However, persistence phenom…
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…
Extended dynamical range as a collective property of excitable cells
Osame Kinouchi
Receptor cells with electrically coupled axons can improve both their input sensitivity and dynamical range due to collective non-linear wave properties. This mechanism is illustra…
Self-organized (quasi-)criticality: the extremal Feder and Feder model
Osame Kinouchi
A simple random-neighbor SOC model that combines properties of the Bak-Sneppen and the relaxation oscillators (slip-stick) models is introduced. The analysis in terms of branching…
Statistical Mechanics of Online Learning of Drifting Concepts : A Variational Approach
Renato Vicente, Osame Kinouchi, Nestor Caticha
We review the application of Statistical Mechanics methods to the study of online learning of a drifting concept in the limit of large systems. The model where a feed-forward netwo…
