WebCoherent feedforward loops can show persistence detection, whereas incoherent feedforward loops show pulse generation and response acceleration. Single-input modules can generate temporal... 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 … earn epi

WebJan 4, 2024 · Specifically, we propose that an incoherent feedback loop mechanism, besides high redundancy, mediates robustness of expression of broadly expressed genes, and we show how redundancy may be a consequence of motif turnover in regulatory sequences, instead of the result of natural selection favouring robustness. Methods 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. ... Meanwhile, the networks linked to metabolism are significantly incoherent (q/q̃ > 1) and have mean trophic ...
