birth Haldan Keffer Hartline Born 22 Dec 1903; died 17 Mar 1983 at age 79. American physiologist who shared (with George Wald and Ragnar Granit) the 1967 Nobel Prize for Physiology or Medicine for his analysis of how the sensory cells of the retina of the eye evaluate the light stimulus. In his early career, he studied the metabolism of nerve cells and in time came to research individual cells in the retina of the eye. He used tiny electrodes to isolate individual fibres in the eyes of horseshoe crabs and frogs. He learned how impulse generation in the sensory cells transmits a code in response to illumination of different intensity and duration. He spent almost half a century advancing the understanding of the neurophysiology of vision. |
