Primes¶
- Criticality
- At \(\sigma = 1\) the system is critical: avalanche size distributions follow a power law \(P(s) \propto s^{-3/2}\) over multiple orders of magnitude, dynamic range and mutual information are maximized, and the system exhibits long-range temporal correlations — a pattern Shew and Plenz (2013) review as the empirical core of the critical-brain hypothesis.
This sourceReview assembling evidence that cortical networks operate near a critical branching ratio of one, with three functional benefits optimized at criticality: dynamic range, information transmission, and information capacity.
Supported in partVerified against the publisher's abstract
The review's abstract backs cortical criticality and dynamic-range optimisation, but says nothing about an s^-3/2 avalanche exponent, mutual information, or long-range temporal correlations.
“Finally, we review quantitative evidence that three functional properties of the cortex are optimized at criticality: 1) dynamic range, 2) information transmission, and 3) information capacity.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
