In this article, a correlation metric κ_{c} is proposed for the inference of the dynamical state of neuronal networks. κ_{C} is computed from the scaling of the correlation length with the size of the observation region, which shows qualitatively different behavior near and away from the critical point of a continuous phase transition. The implementation is first studied on a neuronal network model, where the results of this new metric coincide with those obtained from neuronal avalanche…

Controlling a complex system near its critical point via temporal correlations

It is demonstrated that feedback from the autocorrelation function of the order parameter fluctuations shifts the system towards its critical point, relying on universal properties of critical systems.

Undersampled Critical Branching Processes on Small-World and Random Networks Fail to Reproduce the Statistics of Spike Avalanches

It is found that undersampling modifies avalanche size distributions, extinguishing the power laws observed in critical systems.

Box scaling as a proxy of finite size correlations

Finite-size scaling can be approximated in an experimental system of fixed and relatively small extent, by computing correlations inside of a reduced field of view of various widths (referred to as “box-scaling”).

Disentangling the critical signatures of neural activity

This work finds that power-law neuronal avalanches satisfying the crackling-noise relation coexist with spatial correlations that display typical features of critical systems, and introduces a paradigmatic framework with a common stochastic modulation and pairwise linear interactions inferred from data.

Spontaneous cortical activity in awake monkeys composed of neuronal avalanches

It is shown that ongoing cortical synchronization in awake rhesus monkeys carries the signature of neuronal avalanches, which suggest an organization of ongoing cortex synchronization that is scale-invariant in its three fundamental dimensions—time, space, and local neuronal group size.

What kind of noise is brain noise: anomalous scaling behavior of the resting brain activity fluctuations

Three statistical features which clearly differentiate brain data from naive expectations for random processes are uncovered, and are relevant for the interpretation of the role of fluctuations and variability in brain function in health and disease.

A synaptic organizing principle for cortical neuronal groups

A synaptic organizing principle is discovered that groups neurons in a manner that is common across animals and hence, independent of individual experiences that is speculated to be prescribed Lego-like building blocks of perception.

Long-range correlation in protein dynamics: Confirmation by structural data and normal mode analysis

This work demonstrates that long-range correlations of proteins contribute to many biological processes such as allostery, catalysis, and transportation are encoded in the native topology of the proteins, and quantitatively describes how native proteins balance between order and disorder.

Scale-free correlations in starling flocks

It is suggested that flocks behave as critical systems, poised to respond maximally to environmental perturbations, through scale-free behavioral correlations, which provide each animal with an effective perception range much larger than the direct interindividual interaction range, thus enhancing global response to perturbation.
