feedback loop

[′fēd‚bak ‚lüp]
(control systems)
A closed transmission path or loop that includes an active transducer and consists of a forward path, a feedback path, and one or more mixing points arranged to maintain a prescribed relationship between the loop input signal and the loop output signal. Also known as feedback control loop.

In mammals, circadian rhythm comprises of a network of genes with numerous positive and negative feedback loops [19].
Results: Overall patients with higher glucose levels had poor quality of life (r = -.16, p <.05) but the relationship was not significant in the feedback loop. Whereas along with direct and indirect effect of self-regulation (b =.45, and b =.26 respectively; p <.05) and direct effect of resilience (b =.33, p <.05) on quality of life, Model 2 (without feedback loop) suggested that current glucose level is directly predicted by quality of life (b = -.13, p <.05) and indirectly by resilience and self-regulation through quality of life (b = -.09, and b = -.04 respectively; p <.05).
