RESEARCH INTERESTS

Dr. Berthoud is primarily interested in the role of the nervous system in the processes maintaining energy homeostasis and nutrient intake. This includes the receptors and pathways that allow the peripheral nervous system and the brain to sense the internal metabolic state and availability of important nutrients as well as the external food environment, the neural circuits integrating this information, and the behavioral, autonomic, and endocrine effector pathways leading to regulatory actions. Interests thus impinge on the areas of obesity and anorexia, gastrointestinal and liver physiology, gut-brain interactions, autonomic nervous system, cognitive neurosciences, taste physiology, and functional foods. The largely NIH funded research activities employ behavioral, neuroanatomical, neurochemical, and electrophysiological methods.
