Cellular and Integrative Physiology
Homeostasis refers to the process by which the body maintains a constant internal environment. In the orchestration of homeostasis, brain networks involved in autonomic and neuroendocrine function coordinate multiple peripheral physiological systems through complex network processing. Our laboratory is particularly interested in how the brain monitors, processes, and integrates energy homeostatic signals under normal physiology and pathological disease states.
