For example, negative feedback loops involving insulin and glucagon help to keep blood glucose levels within a narrow concentration range. Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Not surprisingly, therefore, the positive feedback is less common in nature than the negative one. What is the negative feedback loop that controls anxiety? Toxins. It is a part of homeostasis. This hormone moves to the nearby pituitary gland , causing production of thyroid stimulating hormone (TSH), which is then released into the blood stream. Best Buy, the world’s largest consumer electronics retailer, effectively uses a negative feedback loop to improve their customers’ experience. It occurs when the original effect of the stimulus is reduced by the output.
