In physiology, feed-forward control is exemplified by the normal anticipatory regulation of heartbeat in advance of actual physical exertion by the central autonomic network. Feed-forward control can be likened to learned anticipatory responses to known cues (predictive coding). Feedback regulation of the heartbeat provides further adaptiveness to the running eventualities of physical exertion. Feedforward systems are also found in biological control of other variables by … granite mailbox post nashua nh installation

WebNegative feedback loops provide precise control of endocrine secretions (Fig. 13-3 ). The controlled component of the negative feedback loop can be ion concentrations, physical parameters (e.g., blood pressure), and hormone concentrations. Stimulators of endocrine gland secretion also have important trophic effects. WebWe show here that the number of feedback loops in a network, as well as the eigenvalues of associated matrices, is determined by a structural property called trophic coherence, a measure of how neatly nodes fall into distinct levels. ...
