Self-organized bistability and its possible relevance for brain dynamics
Victor Buendía, Serena di Santo, Pablo Villegas +2
Self-organized bistability (SOB) is the counterpart of 'self-organized criticality' (SOC), for systems tuning themselves to the edge of bistability of a discontinuous phase transit…
Time-series thresholding and the definition of avalanche size
Pablo Villegas, Serena di Santo, Raffaella Burioni +1
Avalanches whose sizes and durations are distributed as power laws appear in many contexts. Here, we show that there is a hidden peril in thresholding continuous times series --eit…
Jensen's force and the statistical mechanics of cortical asynchronous states
Victor Buendía, Pablo Villegas, Serena di Santo +3
The cortex exhibits self-sustained highly-irregular activity even under resting conditions, whose origin and function need to be fully understood. It is believed that this can be d…
Non-normality, reactivity, and intrinsic stochasticity in neural dynamics: a non-equilibrium potential approach
Serena di Santo, Pablo Villegas, Raffaella Burioni +1
Intrinsic stochasticity can induce highly non-trivial effects on dynamical systems, including stochastic and coherence resonance, noise induced bistability, noise-induced oscillati…
Landau-Ginzburg theory of cortex dynamics: Scale-free avalanches emerge at the edge of synchronization
Serena di Santo, Pablo Villegas, Raffaella Burioni +1
Understanding the origin, nature, and functional significance of complex patterns of neural activity, as recorded by diverse electrophysiological and neuroimaging techniques, is a…
Self-Organized Bistability Associated With First-Order Phase Transitions
Serena di Santo, Raffaella Burioni, Alessandro Vezzani +1
Self-organized criticality elucidates the conditions under which physical and biological systems tune themselves to the edge of a second-order phase transition, with scale invarian…
