Primes¶
- Criticality
- Each lives at a control-parameter value where the next perturbation may stay local or may cascade across the system, and the size distribution of cascades is governed by a power law whose exponent depends on the system's symmetry class rather than on its microscopic constituents, an empirical pattern Beggs and Plenz (2003) documented for neural avalanches in cortical slices and which has since been replicated across a wide range of preparations.
This sourceExperimental documentation of power-law neural-avalanche size distributions in organotypic cultures and acute slices of rat cortex; empirical anchor of the critical-brain research program the marker cites.
Supported in partVerified against the publisher's abstract
Abstract documents power-law avalanche sizes (exponent -3/2) in rat cortical slices at branching parameter ~1, but says nothing of exponents tracking symmetry class.
“As predicted by theory for a critical branching process, the propagation obeys a power law with an exponent of -3/2 for event sizes, with a branching parameter close to the critical value of 1.”

- Percolation
- Collective behavior. A social movement reaches systemic scale only when local-recruitment density crosses a threshold; threshold models of collective action are percolation models. Neuroscience. Neuronal avalanches, the critical-brain hypothesis, and the seizure threshold as a percolation transition in recurrent excitatory networks.

Abstract reports power-law neuronal avalanches with branching parameter near 1 — the critical-branching half of the claim; it says nothing of seizure thresholds or percolation.

The abstract supports critical, power-law neuronal avalanches with a branching parameter near 1, but frames them as a critical branching process, not as a percolation threshold in synaptic connectivity.

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 3 of 3 citations: 3 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.
