A decline in function as a result of stimulation is known as negative feedback. When there is negative feedback, the output of a certain system or reaction is reduced.
The homeostatic process is known as a negative feedback mechanism when the response causes the initial stimulus to decrease. Positive feedback mechanisms are those where the response improves upon the initial stimulus. Feedback loops react to environmental changes or stimuli to keep systems operating close to their set point or ideal level. When an input or stimulus is affected or influenced by an output or response from a loop, this is known as feedback.
