Knowra Walter Rudolf Hess Walter Rudolf Hess Walter Rudolf Hess was a Swiss physiologist whose experiments on the diencephalon linked brain activity to the coordination of internal organs. He shared the 1949 Nobel Prize in Physiology or Medicine.
Diencephalon : The brain region between the cerebral hemispheres and midbrain, including the thalamus and hypothalamus. Hess mapped how stimulation within this region produced coordinated visceral responses.
University of Zurich : A public research university in Zurich, Switzerland, founded in 1833. Hess studied medicine there and later held a professorship in physiology.
Egas Moniz : A Portuguese neurologist who received the 1949 Nobel Prize in Physiology or Medicine for developing cerebral angiography. Moniz shared the 1949 Nobel Prize with Hess for distinct research.
Neuroendocrinology : The study of interactions between the nervous system and endocrine system. Hess’s work supported investigation of how brain regions coordinate hormonal and bodily responses.
Defense reaction : A coordinated set of behavioral and physiological responses that prepares an animal to confront or escape danger. Hess elicited defense-like responses by stimulating particular diencephalic regions.
Hypothalamus : A brain region that regulates autonomic activity, endocrine function, temperature, hunger, and other bodily states. Its stimulation was central to Hess’s account of integrated autonomic responses.
Ophthalmology : The medical specialty concerned with the eyes, vision, and their disorders. Hess began his medical career as an ophthalmologist before turning to physiology.
Walter Rudolf Hess (neuroscientist) : A German-born Swiss neuroscientist, distinct from the Swiss Nobel laureate Walter Rudolf Hess. The shared name can cause confusion with Hess, the physiologist featured here.
Psychosomatic medicine : The study and treatment of interactions between psychological processes and physical health. Hess’s research linked emotional states and brain activity with bodily functions.
Sham rage : A pattern of apparent rage, including autonomic changes, provoked in animals by brain lesions or stimulation. Hess’s stimulation experiments helped demonstrate that rage-like behavior could be evoked without an external threat.
