About 10,000 papers for “Negative feedback”

Negative feedback

Geoffrey Brooker · 2021

Abstract Negative feedback is an essential constituent of any control system. It is illustrated for the case of an electronic voltage amplifier. Formal definitions are given of positive and negative feedback. Feedback can be used to adjust the amplifier's frequency response. Distortion, meaning generation of new and unwanted frequencies (harmonics, sums, differences), is reduced by a factor equal to the “return difference”.

<p>Abbreviations: L, Left; R, right; DL, dorsolateral; VL, ventrolateral; CC, cingulate cortex; PMC, premotor cortex; PPC, posterior parietal cortex; TC, temporal cortex; pSMA, presupplementay motor area. When no asterisk is indicated, p<0.05 corrected; *p<0.001 uncorrected. Cluster sizes are reported in mm3. sc indicates that the peak is part of the same cluster as the peak listed immediately above in the table. The numbers in parentheses refer to architectonic areas.</p>

Comparison of a System with Negative Feedback and without Negative Feedback

Gil Hornung (83596), Naama Barkai (7814) · Figshare · 2015

<div><p>(A) A system with negative feedback (pink) and without negative feedback (blue) were compared in terms of (B) the output noise in response to fluctuations in the input (green), and (C) the deterministic response of the two systems to a 2-fold change in the input.</p><p>(D) Noise amplification versus susceptibility for negative feedback with different Hill coefficients. The color-code is the level of saturation of the input promoter. Sensitivity was calculated by solving the steady-state equations after a 1% change in the input levels, and noise amplification was the result of stochastic simulations (<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.0040008#s4" target="_blank">Methods</a>).</p></div>
