Query: Quasi-universal scaling in mouse-brain neuronal activity stems from
  edge-of-instability critical dynamics   The brain is in a state of perpetual reverberant neural activity, even in the
absence of specific tasks or stimuli. Shedding light on the origin and
functional significance of such activity is essential to understanding how the
brain transmits, processes, and stores information. An inspiring, albeit
controversial, conjecture proposes that some statistical characteristics of
empirically observed neuronal activity can be understood by assuming that brain
networks operate in a dynamical regime near the edge of a phase transition.
Moreover, the resulting critical behavior, with its concomitant scale
invariance, is assumed to carry crucial functional advantages. Here, we present
a data-driven analysis based on simultaneous high-throughput recordings of the
activity of thousands of individual neurons in various regions of the mouse
brain. To analyze these data, we construct a unified theoretical framework that
synergistically combines cutting-edge methods for the study of brain activity
(such as a phenomenological renormalization group approach and techniques that
infer the general dynamical state of a neural population), while designing
complementary tools. This unified approach allows us to uncover strong
signatures of scale invariance that is "quasi-universal" across brain regions
and reveal that these areas operate, to a greater or lesser extent, at the edge
of instability. Furthermore, this framework allows us to distinguish between
quasi-universal background activity and non-universal input-related activity.
Taken together, the following study provides strong evidence that brain
networks actually operate in a critical regime which, among other functional
advantages, provides them with a scale-invariant substrate of activity in which
optimal input representations can be sustained.
