Maximum entropy models of neuronal populations at and off criticality
T. S. A. N. Simões, F. Lombardi, D. Plenz +2
Empirical evidence of scaling behaviors in neuronal avalanches suggests that neuronal populations in the brain operate near criticality. Departure from scaling in neuronal avalanch…
Allometric scaling of brain activity explained by avalanche criticality
Tiago S. A. N. Simões, José S. Andrade, Hans J. Herrmann +2
Allometric scaling laws, such as Kleiber's law for metabolic rate, highlight how efficiency emerges with size across living systems. The brain, with its characteristic sublinear sc…
Generalized Wilson-Cowan model with short term synaptic plasticity
Tommaso Trabocchi, Raffaella Burioni, Lucilla de Arcangelis +1
A generalized version of the Wilson-Cowan (WC) model is proposed which accounts for the evolution of the synaptic resources. Adiabatic elimination of the fast variables is performe…
Modeling public opinion control by a charismatic leader
Tiago S. A. N. Simões, Antonio Coniglio, Hans J. Herrmann +1
We study the average long-time behavior of the binary opinions of a social group with peer-to-peer interactions under the influence of an external bias and a persuadable leader, a…
