Synaptic balance due to homeostatically self-organized quasicritical dynamics
Mauricio Girardi-Schappo, Ludmila Brochini, Ariadne A. Costa +2
Recent experiments suggested that homeostatic regulation of synaptic balance leads the visual system to recover and maintain a regime of power-law avalanches. Here we study an exci…
Self-organized critical balanced networks: a unified framework
Mauricio Girardi-Schappo, Ludmila Brochini, Ariadne A. Costa +2
Asynchronous irregular (AI) and critical states are two competing frameworks proposed to explain spontaneous neuronal activity. Here, we propose a mean-field model with simple stoc…
Metastability and Multiscale Extinction Time on a Finite System of Interacting Stochastic Chains
L. Brochini, M. Abadi
We studied metastability and extinction time of a finite system with a large number of interacting components in discrete time by means of analytical and numerical investigation. T…
Stochastic oscillations produce dragon king avalanches in self-organized quasi-critical systems
O. Kinouchi, L. Brochini, A. A. Costa +2
In the last decade, several models with network adaptive mechanisms (link deletion-creation, dynamic synapses, dynamic gains) have been proposed as examples of self-organized criti…
Self-Organized Supercriticality and Oscillations in Networks of Stochastic Spiking Neurons
Ariadne A. Costa, Ludmila Brochini, Osame Kinouchi
Networks of stochastic spiking neurons are interesting models in the area of Theoretical Neuroscience, presenting both continuous and discontinuous phase transitions. Here we study…
Phase transitions and self-organized criticality in networks of stochastic spiking neurons
L. Brochini, A. A. Costa, M. Abadi +3
Phase transitions and critical behavior are crucial issues both in theoretical and experimental neuroscience. We report analytic and computational results about phase transitions a…
