Definition

Allostasis is the maintenance of viable physiological organization through change, particularly anticipatory regulation of bodily requirements. The corpus distinguishes this from merely correcting a present deviation and connects it with embodied value, learning and interoceptive inference. Successful regulation remains bounded: chronic overload can produce breakdown rather than unlimited adaptive benefit.

Explanation

AB introduces allostasis beside homeostasis as anticipatory regulation, retaining the bodily work needed to remain far from equilibrium. RB2 describes neural learning as value-dependent: biologically significant conditions bias circuit selection and action rather than an otherwise detached intellect first deciding what should matter.

In the predictive-brain discussion, a generative model concerns the internal milieu as well as external objects. Autonomic and behavioral activity are coordinated so physiological variables remain within viable bounds. This supplies a particular model of allostatic organization, not a claim that every anticipatory process requires conscious forecasting.

RB1’s McEwen-attributed stress discussion supplies a limit: adaptation under challenge can become breakdown under chronic overload. The term should therefore not imply that every disturbance is beneficial, that bodily stability is effortless, or that a philosophical analogy establishes an individual clinical conclusion.
