The spontaneous replay of patterns of activity related to past experiences and memories is a
striking feature of brain activity, as is the coherent activation of sets of brain areas …

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 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 …

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

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 …

Scale-free dynamics, with a power spectrum following P∝ f− β, are an intrinsic feature of
many complex processes in nature. In neural systems, scale-free activity is often neglected …

Recent studies have identified broadband phenomena in the electric potentials produced by
the brain. We report the finding of power-law scaling in these signals using subdural …

Spontaneous neuronal activity is an important property of the cerebral cortex but its
spatiotemporal organization and dynamical framework remain poorly understood. Studies in …

Despite the vast progress and achievements in systems biology and integrative physiology
in the last decades, there is still a significant gap in understanding the mechanisms through …
