Walter Hess

Walter Hess was a Swiss physiologist and Nobel laureate known for his research on the brain's role in regulating behavior. He specifically studied how electrical stimulation of certain brain areas, particularly the hypothalamus, influences emotions like fear, aggression, and pleasure in animals. His work helped uncover the neural basis of these emotional responses, contributing significantly to neuroscience and understanding of brain-behavior relationships. Hess’s findings laid the foundation for exploring how specific brain regions control motivation and emotional states in humans and animals.
