Walter Rudolf Hess

Walter Rudolf Hess was a Swiss neuroscientist who won the Nobel Prize in Physiology or Medicine in 1949 for his groundbreaking work on the brain’s control of vital bodily functions. He conducted experiments that mapped how specific areas of the brain regulate activities such as blood pressure, temperature, and digestion. By stimulating certain parts of the brain in animals, he revealed how the central nervous system manages essential processes without conscious effort. His research greatly advanced our understanding of how the brain maintains homeostasis and responded to internal and external changes.
