Walter Cannon

Walter Cannon was an influential American physiologist active in the early 20th century, best known for his work on homeostasis and the concept of the 'fight or flight' response. His research laid the groundwork for understanding the physiological processes that regulate bodily functions and responses to stress. Cannon's identification of the hypothalamic-intestinal axis continues to inform current studies related to hunger and appetite, highlighting the complex interplay between the brain and digestive processes.
