Movement, cognition and perception arise from the collective activity of neurons within
cortical circuits and across large-scale systems of the brain. While the causes of single …

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 …

The human organism comprises various physiological and organ systems, each with its own
structural organization and functional complexity, leading to complex, transient, fluctuating …

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 …

Relatively recent work has reported that networks of neurons can produce avalanches of
activity whose sizes follow a power law distribution. This suggests that these networks may …

Rapidly growing empirical evidence supports the hypothesis that the cortex operates near
criticality. Although the confirmation of this hypothesis would mark a significant advance in …

Hallmarks of criticality, such as power-laws and scale invariance, have been empirically
found in cortical-network dynamics and it has been conjectured that operating at criticality …

Criticality has gained widespread interest in neuroscience as an attractive framework for
understanding the character and functional implications of variability in brain activity. The …

What constitutes normal cortical dynamics in healthy human subjects is a major question in
systems neuroscience. Numerous in vitro and in vivo animal studies have shown that …
