Haldan Keffer Hartline Haldan Keffer Hartline ForMemRS (December 22, 1903 – March 17, 1983) was an American physiologist who was a co-recipient (with George Wald and Ragnar Granit ) of the 1967 Nobel Prize in Physiology or Medicine for his work in analyzing the neurophysiological mechanisms of vision. Haldan Hartline did his undergraduate studies at Lafayette College in Easton, Pennsylvania, graduating in 1923. He began his study of retinal electrophysiology as
55-404: The electrical responses of the retinas of certain arthropods , vertebrates , and mollusks , because their visual systems are much simpler than those of humans and thus easier to study. He concentrated his studies on the eye of the horseshoe crab ( Limulus polyphemus ). Using minute electrodes, he obtained the first record of the electrical impulses sent by a single optic nerve fibre when
66-668: The integration of visual information. In 1948, Hartline was elected to the United States National Academy of Sciences . He was elected to the American Philosophical Society in 1952 and the American Academy of Arts and Sciences in 1957. He was elected to the inaugural class of Fellows of the Optical Society (OSA) of America in 1959. Later, OSA elected him an Honorary Member in 1980. Hartline
77-480: The receptors connected to it are stimulated by light. He found that the photoreceptor cells in the eye are interconnected in such a way that when one is stimulated, others nearby are depressed , thus enhancing the contrast in light patterns and sharpening the perception of shapes. Hartline thus built up a detailed understanding of the workings of individual photoreceptors and nerve fibres in the retina, and he showed how simple retinal mechanisms constitute vital steps in

Hartline joined the staff of Rockefeller University , New York City, in 1953 as professor of neurophysiology. Hartline investigated
