How critical is brain criticality?

J O'Byrne, K Jerbi - Trends in Neurosciences, 2022 - cell.com
Criticality is the singular state of complex systems poised at the brink of a phase transition
between order and randomness. Such systems display remarkable information-processing …

Integrated information theory: from consciousness to its physical substrate

G Tononi, M Boly, M Massimini, C Koch - Nature reviews neuroscience, 2016 - nature.com

Toward naturalistic neuroscience: Mechanisms underlying the flattening of brain hierarchy in movie-watching compared to rest and task

ML Kringelbach, YS Perl, E Tagliazucchi, G Deco - Science Advances, 2023 - science.org

and resting state to using ecological relevant, naturalistic movies. We leveraged a large …

Colloquium: Criticality and dynamical scaling in living systems

MA Munoz - Reviews of Modern Physics, 2018 - APS
A celebrated and controversial hypothesis suggests that some biological systems—parts,
aspects, or groups of them—may extract important functional benefits from operating at the …

Criticality in the brain: A synthesis of neurobiology, models and cognition

L Cocchi, LL Gollo, A Zalesky, M Breakspear - Progress in neurobiology, 2017 - Elsevier
Cognitive function requires the coordination of neural activity across many scales, from
neurons and circuits to large-scale networks. As such, it is unlikely that an explanatory …

The entropic brain-revisited

RL Carhart-Harris - Neuropharmacology, 2018 - Elsevier
The entropic brain hypothesis proposes that within upper and lower limits, after which
consciousness may be lost, the entropy of spontaneous brain activity indexes the …

Consciousness is supported by near-critical slow cortical electrodynamics

D Toker, I Pappas, JD Lendner… - Proceedings of the …, 2022 - National Acad Sciences
Mounting evidence suggests that during conscious states, the electrodynamics of the cortex
are poised near a critical point or phase transition and that this near-critical behavior …
