Extractions: Dictionaries: General Computing Medical Legal Encyclopedia Word: Word Starts with Ends with Definition American physiologist who was a cowinner (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. Hartline began his study of retinal electrophysiology as a National Research Council Fellow at Johns Hopkins University, Baltimore, receiving his M.D. in 1927. After attending the universities of Leipzig and Munich as an Eldridge Johnson traveling research scholar, he became professor of biophysics and chairman of the department at Johns Hopkins in 1949. He joined the staff of Rockefeller University, New York City, in 1953 as professor of neurophysiology. Hartline investigated the electrical responses of the retinas of certain arthropods, vertebrates, and mollusks because their visual systems are much simpler than those of humans and are thus easier to study. He concentrated his studies on the eye of the horseshoe crab (Limulus polyphemus). Using minute electrodes in his experiments, he obtained the first record of the electrical impulses sent by a single optic nerve fibre when the receptors connected to it are stimulated by light. He found that the receptor 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 the integration of visual information.

Extractions: Main Page See live article Alphabetical index The Johns Hopkins University is an elite institution of higher learning located in Baltimore, Maryland . Among the world's most prestigious schools, the University opened February 22 , with the stated goal of "The encouragement of research ... and the advancement of individual scholars, who by their excellence will advance the sciences they pursue, and the society where they dwell." The University's first president was visionary educator Daniel Coit Gilman , and its motto is "Veritas Vos Liberabit," Latin meaning "The Truth Shall Make You Free." It is named for Johns Hopkins , who left seven million dollars in his will for the foundation of The Johns Hopkins University and The Johns Hopkins Hospital . Johns Hopkins was the first research university in the United States , founded on the model of German research institutions. As such, it was the first American university to offer an undergraduate major (as opposed to a purely liberal arts curriculum), and the first American university to grant doctoral degrees. The University was an all-male institution until 1970. Johns Hopkins offers superior undergraduate programs based at the Homewood Campus in Baltimore: The and the G.W.C. Whiting School of Engineering

Earlier, in 1948, Walter Rudolf Hess perfected a method of implanting electrodes in the brains of rats and was thus able to localize centers of the brain associated with certain instincts. Charles Francis Brush U.S. inventor and industrialist who devised an electric arc lamp and a generator that produced a variable voltage controlled by the load and a constant current. It was adopted throughout the United States and abroad during the 1880's. The arc light preceded Edison's incandescent light bulb in commercial use and was suited to applications where a bright light was needed, such as street lights and lighting in commercial and public buildings. He assembled his first dynamo in the summer of 1876, resulting in a patent for his

Extractions: American organic chemist Sarett and several collaborators initiated an alternative synthesis commencing with raw materials derivable from coal, air, lime, and water. This led to the first route independent of naturally occurring starting materials. Sarett was the 1975 recipient of the National Medal of Science. Grote Reber U.S. astronomer and radio engineer who built the first radio telescope and was largely responsible for the early development of radio astronomy, an entirely study of the universe. He worked as an amateur, devoting nights and weekends to this hobby, Reber constructed a 9-meter dish antenna in his back yard and built three different detectors before finding signals at a frequency of 160 MHz in 1939. His 1940 and 1944 publications of articles titled Cosmic Static in the Astrophysical Journal marked the beginning of intentional radio astronomy. He was the first to express received radio signals in terms of flux density and brightness, first to find evidence that galactic radiation is non-thermal, and first to produce radio maps of the sky.
