Neuronal avalanches in spontaneous activity in vivo.
Many complex systems give rise to events that are clustered in space and time, thereby establishing a correlation structure that is governed by power law statistics. In the cortex, such clusters of activity, called "neuronal avalanches," were recently found in local field potentials (LFPs) of spontaneous activity in acute cortex slices, slice cultures, the developing cortex of the anesthetized ...

متن کاملSpontaneous cortical activity in awake monkeys composed of neuronal avalanches.
Spontaneous neuronal activity is an important property of the cerebral cortex but its spatiotemporal organization and dynamical framework remain poorly understood. Studies in reduced systems--tissue cultures, acute slices, and anesthetized rats--show that spontaneous activity forms characteristic clusters in space and time, called neuronal avalanches. Modeling studies suggest that networks with...
متن کاملActivity dependent model for neuronal avalanches
Cortical networks exhibit diverse patters of spontaneous neural activity, including oscillations, synchrony and waves. The spontaneous activity often in addition exhibits slow alternations between high activity periods, or bursts, followed by essentially quiet periods. Bursts can last from a few to several hundreds of milliseconds and, if analysed at a finer temporal scale, show a complex struc...
متن کاملNeuronal Avalanches
It has recently been suggested that, in order to provide the richness of behavior which is seen empirically, the brain must operate in a critical regime between a phase of order and disorder [1]. In particular, such critical behavior is exhibited in what is termed neuronal avalanches. These cascades of synaptic activity have been seen both in vitro and in vivo [6]. Several models have been put ...
