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.

claimThe cybernetic model of homeostasis assumes that health coincides with a state of equilibrium, stability, or balance.

claimBy applying the cybernetic model to biological homeostasis, scientists associate biological regulation with compensation for perturbations, aiming to return the system to an initial or stable state defined by a setpoint.

claimUnder the cybernetic model, a system maintaining constant states is expected to possess a mechanism of negative feedback consisting of a setpoint, a comparator/integrator/controller, and effectors that activate when the regulated variable departs from the setpoint.

claimIn cybernetic models, negative feedback involves comparing the current value of a variable against a setpoint, where any mismatch results in an error signal that initiates corrective action.

claimMedical education often characterizes homeostasis using a cybernetic model based on negative feedback involving a setpoint, which is considered a standard for physiological education.

perspectiveThe authors argue that the notion of homeostasis has been hindered by a narrowed account based on the cybernetic model of negative feedback to a setpoint, which equates health with balance and healing with returning to a normal state.

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.

claimConceptual problems arise in the cybernetic model of homeostasis when limitations are overlooked, when a single mechanism is identified with the whole phenomenon of regulation, and when generalizations are made from specific mechanisms to the functioning of a whole organism.

claimInterpretations of health and homeostasis based on the cybernetic model vary based on whether they prioritize the stability of individual variables, an integrated set of variables, or the system's general capacity to respond to perturbations.
