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 …

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 …

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 …

Deep non-rapid eye movement sleep (NREM) and general anesthesia with propofol are
prominent states of reduced arousal linked to the occurrence of synchronized oscillations in …

Highlights•Numerous neurocognitive factors contribute to sustained attention.•Attention
fluctuates alongside shifting arousal, effort, and resource allocation.•An information …

Brain activity observed at many spatiotemporal scales exhibits a 1/f-like power spectrum,
including neuronal membrane potentials, neural field potentials, noninvasive …

Neuroscience has made considerable progress in unraveling the neural correlates of mental
phenomena like self, consciousness, and perception. However, the “common currency” …

Research in cognitive neuroscience has extensively demonstrated that the temporal
dynamics of brain activity are associated with cognitive functioning. The temporal dynamics …

The neural criticality hypothesis states that the brain may be poised in a critical state at a
boundary between different types of dynamics. Theoretical and experimental studies show …

Since the first measurements of neuronal avalanches, the critical brain hypothesis has
gained traction. However, if the brain is critical, what is the phase transition? For several …
