claimThe Predictive Anticipatory Oscillation (PAO) hypothesis posits that the capacity for expressing context-sensitive and heterogeneous phenotypes of health is a function of the brain's proximity to the state of criticality, as supported by research from Beggs and Timme (2012), Shew and Plenz (2013), and Cocchi et al. (2017).

claimThe homeostasis paradigm utilizes linear models, whereas the Paradigm of Allostatic Orchestration utilizes models based on complexity, criticality, and non-linear dynamics.

claimHealth is hypothesized to be an allostatic state of optimal anticipatory oscillation, which relates to the state of criticality, defined as a mathematical point of poise between phases on the border between order and disorder.

claimThe PAO (Paradigm of Allostatic Organization) construct of the allostatic state represents the integrated totality of brain-body interactions and optimal anticipatory oscillation, which is potentially a function of the mathematically-defined state of criticality.

claimThe state of criticality, in conjunction with genetic substrates and other factors, can produce evolutionary phenomena including natural selection, sexual selection, altruism, cooperation, and beauty.

claimThe tendency to maintain a state of criticality, defined as a point of mathematical poise between phases on the border between order and disorder, is hypothesized to explain the likelihood of expressing optimal anticipatory oscillations.

claimThe Paradigm of Allostatic Organization (PAO) aligns with the philosophy of freedom, and Bettinger (2017) suggests that the subjective feeling of freedom of choice may be the experiential dimension of the objectively defined state of criticality.

claimIn statistical physics and the Predictive Anticipatory Oscillation (PAO) model, 'criticality' refers to the point of mathematical balance between phases of a complex system, or a state of poise on the border between order and disorder, also known as the 'edge of chaos.'

claimCortical functioning at criticality permits optimizations of dynamic range, fidelity of information transmission, and information capacity, according to Shew and Plenz (2013).

claimDevices and tools designed to support the optimality of complex system dynamics (Lee et al., 2019) and the state of criticality (Ros et al., 2016) are methods to focus on the brain itself for allostatic health.

claimThe relationship between criticality and optimal anticipatory oscillation may be non-linear, as many brain functions likely operate on the basis of power laws, as suggested by Thiel (2014), Bettinger (2017), and Kasagi et al. (2017).
