The Ghost of Stochastic Resonance: An Introductory Review
Pablo Balenzuela, Holger Braun, Dante R. Chialvo
Nonlinear systems driven by noise and periodic forces with more than one frequency exhibit the phenomenon of Ghost Stochastic Resonance (GSR) found in a wide and disparate variety…
Point process analysis of large-scale brain fMRI dynamics
Enzo Tagliazucchi, Pablo Balenzuela, Daniel Fraiman +1
Functional magnetic resonance imaging (fMRI) techniques have contributed significantly to our understanding of brain function. Current methods are based on the analysis of \emph{gr…
The collective brain is critical
Enzo Tagliazucchi, Dante R. Chialvo
The unique dynamical features of the critical state endow the brain with properties which are fundamental for adaptive behavior. This proposal, put forward with Per Bak several yea…
Spike Avalanches Exhibit Universal Dynamics across the Sleep-Wake Cycle
Tiago L. Ribeiro, Mauro Copelli, Fábio Caixeta +4
Scale-invariant neuronal avalanches have been observed in cell cultures and slices as well as anesthetized and awake brains, suggesting that the brain operates near criticality, i.…
