  2. File:Negative Feedback Loop Diagram for Human Body ...

    en.wikipedia.org/wiki/File:Negative_Feedback...

    English: An important negative feedback mechanism in human beings is the ability to maintain body temperature. When the body temperature is too high or too low, the blood vessels will change size accordingly to bring the body’s temperature back to normal.

  3. Negative feedback - Wikipedia

    en.wikipedia.org/wiki/Negative_feedback

    A simple negative feedback system is descriptive, for example, of some electronic amplifiers. The feedback is negative if the loop gain AB is negative.. Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by ...

  4. Perceptual control theory - Wikipedia

    en.wikipedia.org/wiki/Perceptual_control_theory

    Perceptual control theory (PCT) is a model of behavior based on the properties of negative feedback control loops. A control loop maintains a sensed variable at or near a reference value by means of the effects of its outputs upon that variable, as mediated by physical properties of the environment.

  6. CLAW hypothesis - Wikipedia

    en.wikipedia.org/wiki/CLAW_hypothesis

    The CLAW hypothesis proposes a negative feedback loop that operates between ocean ecosystems and the Earth's climate. [1] The hypothesis specifically proposes that particular phytoplankton that produce dimethyl sulfide are responsive to variations in climate forcing, and that these responses act to stabilise the temperature of the Earth's atmosphere.

  7. Bistability - Wikipedia

    en.wikipedia.org/wiki/Bistability

    Bistability can be generated by a positive feedback loop with an ultrasensitive regulatory step. Positive feedback loops, such as the simple X activates Y and Y activates X motif, essentially link output signals to their input signals and have been noted to be an important regulatory motif in cellular signal transduction because positive ...

  8. Allostasis - Wikipedia

    en.wikipedia.org/wiki/Allostasis

    The brain is able to overcome negative feedback in these localized systems and continuously evaluate the body's internal set-points. By doing so, the body can regulate its resources and energy storage efficiently. Another key component of allostasis is the brain's perception and subsequent adaptation to chronic stress.

  9. Electrothermal feedback - Wikipedia

    en.wikipedia.org/wiki/Electrothermal_feedback

    The decrease in Joule heating will cause the device to return to its equilibrium temperature. This is known as negative electrothermal feedback, as the change in Joule heating opposes the change in temperature. If the device is instead biased with a constant current I, the Joule power P = I 2 R will increase if the temperature increases. Thus ...
