Biological feedback is a research area that focuses on the body's ability to regulate and maintain internal balance through various mechanisms. This process involves receiving information from the body's internal and external environment, processing that information, and making appropriate adjustments to maintain homeostasis. Biological feedback can occur at various levels, such as the molecular, cellular, and physiological levels, and plays a crucial role in processes like temperature regulation, hormone secretion, and immune response. Researchers in this area study the mechanisms of biological feedback and how they can be manipulated to treat various diseases and disorders.
