4.1.2 Feedback loops Feedback loops are, “The secondary effects of a direct effect of one variable on another, they cause a change in the magnitude of that effect. A positive feedback enhances the effect; a negative feedback dampens it” (Walker and Salt, 2006, p. 163). Feedback lo...
When Vinchanges, negative feedback changes the input to the amplifier in order to counteract the effect of the change in Vin. Conversely, positive feedback increases the effects of the change in Vin. The output (Vout) is equal to the sum of the Vinand feedback signals multipl...

In this review, an overview of some exciting recent experimental studies focusing on positive-feedback-driven behaviors such as signal amplification and rapid switching, response coherence, and output maintenance will be presented. Moreover, the biological contexts of these positive-feedback loops, the...
This present article incorporates an understanding of feedback from systems theory that is broader than the common application of the concept in the field of behavior analysis, and considers several examples that illustrate how positive-feedback loops between multiple metacontingencies may result in the...
dual interlinked positive feedback loops, which can behave as a bistable switch. We study the responses of five types of bistable switches to noisy stimuli. Noise-induced transitions between two states are investigated in detail by using energy landscape. We find that the switch composed of interl...

Positive feedback: the amplification of the end product of a physiological process to enhance the effect. Positive feedback systems are cyclic and work to amplify your body's response to a stimulus. Negative feedback: the dampening of the end product of a physiological proces...
Bistability is ubiquitous in biological systems. For example, bistability is found in many reaction networks that involve the control and execution of important biological functions, such as signaling processes. Positive feedback loops, composed of speci
