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 …

Highlights•The criticality hypothesis has received major attention in the past 25 years.•We
revise and discuss the experimental and conceptual controversies.•We propose that cortical …

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 …

Homeostatic mechanisms stabilize neuronal activity in vivo, but whether this process gives
rise to balanced network dynamics is unknown. Here, we continuously monitored the …

Understanding how brains process information is an incredibly difficult task. Amongst the
metrics characterising information processing in the brain, observations of dynamic near …

Due to the size and opacity of vertebrate brains, it has until now been impossible to
simultaneously record neuronal activity at cellular resolution across the entire adult brain. As …

The human brain displays a rich repertoire of states that emerge from the microscopic
interactions of cortical and subcortical neurons. Difficulties inherent within large-scale …

Current efforts to achieve neuromorphic computation are focused on highly organized
architectures, such as integrated circuits and regular arrays of memristors, which lack the …

Cortical neurons emit seemingly erratic trains of action potentials or “spikes,” and neural
network dynamics emerge from the coordinated spiking activity within neural circuits. These …

Sleep is assumed to subserve homeostatic processes in the brain; however, the set point
around which sleep tunes circuit computations is unknown. Slow-wave activity (SWA) is …
