Homeostasis is fundamentally defined by the cybernetic model as a process that relies on setpoints to maintain physiological stability through negative feedback, as described in [1], [2], and [3]. The setpoint serves as the target reference value that feedback mechanisms aim to restore, making it an essential component of the homeostatic process according to [4], [5], and [6].

claimIn the cybernetic model of homeostasis, when physiological variables are perturbed, feedback mechanisms detect the variation and trigger response mechanisms to return the variables to the reference value established by the setpoint.
quote“homeostasis would not be possible without setpoints, feedback, and regulation.”
claimThe cybernetic idea of homeostasis posits that feedback mechanisms of error correction maintain physiological variables stable around specific setpoints.
claimWilliam Bechtel and Bich identify three core topics in the debate over homeostasis: (1) setpoints are variable and adjustable rather than fixed; (2) physiological regulation involves anticipating future variation rather than just responding to it; and (3) the notion of a setpoint is inaccurate for describing biological systems.
claimMedical education often characterizes homeostasis using a cybernetic model based on negative feedback involving a setpoint, which is considered a standard for physiological education.
claimThe traditional cybernetic interpretation of homeostasis defines health as the maintenance of stability and balance, where physiological states are preserved or returned to a setpoint after a perturbation.
claimThe cybernetic view of homeostasis associates the concept with negative feedback mechanisms designed to restore a setpoint.
claimThe narrow cybernetic interpretation of homeostasis, which relies on feedback mechanisms and setpoints, emphasizes stability and balance as the primary hallmarks of health, viewing change or imbalance as conditions to be counteracted.
claimThe cybernetic model of homeostasis, which relies on negative feedback to a setpoint, associates health with balance or stability and defines healing as returning to an initial or normal state after a perturbation.
perspectiveThe authors of the article argue that current accounts connecting health with homeostasis share common limits because they rely, to varying degrees, on a cybernetic perspective of homeostasis based on feedback and setpoints.
claimLibretti and Puckett (2023) claim that homeostasis would not be possible without setpoints, feedback, and regulation.

referenceThe key components of homeostasis include a setpoint (target value), sensors (receptors like thermoreceptors), a controlled variable (the parameter being regulated), a comparator/integrator (like the hypothalamus), and effectors (organs or tissues that execute corrective actions).
