Who is Walter Bradford Cannon?June 26, 2021
American physiologist Walter Bradford Cannon, born in Wisconsin in 1871, is known for his work on X-rays and the Cannon-Brad theory.
Cannon, who studied at Harvard University, served as a professor of physiology at the same university and was elected a member of the American National Academy of Sciences.
He announced his theories to the scientific community in his book The Wisdom of the Body, published in 1932. He was recognized as one of the most respected scientists of the century with his General Psychology research published in 2002.
During his studies at Harvard University, Cannon used newly discovered X-rays to study the swallowing mechanism and stomach motility. He published his first paper on his research in the first issue of the American Journal of Physiology in January 1898.
During his career, Cannon conducted studies on many important subjects such as digestion, bodily effects of emotional excitement, wound-shock research, stable states of the organism, chemical mediation of nerve impulses, chemical sensitivity of nerve isolated organs, and shed light on the scientific community.
In the Cannon-Bard theory, which Cannon developed with physiologist Philip Bard, he tried to explain people’s reactions to the emotions they felt.
He proposed the Dry Mouth Hypothesis that people are thirsty because their mouth is dry. In his experiment on dogs with cuts in their throats and small tubes inserted into these cuts, he discovered that although no water reached their stomachs due to the tubes, dogs’ thirst was quenched with water placed in their mouths.
