Biology negative feedback definition
WebThe feedback signal is usually much smaller than the input stimulus, but exerts a powerful stabilizing and linearizing effect on the whole system. Negative feedback, long used to improve the stability and quality of electronic circuits, is now known to be an important principle in a wide range of biological and physiological systems. WebPositive feedback occurs when a living system amplifies a stimulus to move the body away from steady state. Similar to negative feedback, the four steps of positive feedback mechanisms include stimulation, reception, processing, and response. However, instead of bringing changes back, it strengthens/amplifies it!
