Alexander Forbes (neurophysiologist)
Alexander Forbes (May 14, 1882, Milton, Massachusetts – March 27, 1965, Milton, Massachusetts) was an American electrophysiologist, neurophysiologist, and professor of physiology at Harvard Medical School. He "had an enormous impact on the physiology and neuroscience of the twentieth century." Biography Born into the Boston Brahmin upper class Forbes family, Alexander Forbes's father was William Hathaway Forbes and his mother was Edith Emerson Forbes, the daughter of Ralph Waldo Emerson. From 1889 to 1899 Alexander Forbes attended Milton Academy. There he particularly liked the physics and advanced Greek taught by James Hattrick Lee. For the academic year 1899–1900, Forbes did not pursue formal education but spent time on the Forbes family's Wyoming cattle ranch, camped in the Bighorn Mountains, worked briefly in a Maine electro-chemical mill, and travelled in the Pacific Coast states until the beginning of summer 1900; during that summer he visited "Switzerland, France, Hollan ...

Walter Bradford Cannon
Walter Bradford Cannon (October 19, 1871 – October 1, 1945) was an American physiologist, professor and chairman of the Department of Physiology at Harvard Medical School. He coined the term "fight or flight response", and developed the theory of homeostasis. He popularized his theories in his book ''The Wisdom of the Body'', first published in 1932. Life and career Cannon was born on October 19, 1871, in Prairie du Chien, Wisconsin, the son of Colbert Hanchett Cannon and his wife Wilma Denio. His sister Ida Maud Cannon (1877-1960) became a noted hospital social worker at Massachusetts General Hospital. In his autobiography ''The Way of an Investigator'', Cannon counts himself among the descendants of Jacques de Noyon, a French Canadian explorer and coureur des bois. His Calvinist family was intellectually active, including readings from James Martineau, John Fiske (philosopher), and James Freeman Clarke. Cannon's curiosity also led him to Thomas Henry Huxley, John Tyndall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilfred Grenfell
Sir Wilfred Thomason Grenfell (28 February 1865 – 9 October 1940) was a British medical missionary to Newfoundland, who wrote books on his work and other topics. Early life and education He was born at Parkgate, Cheshire, England, on 28 February 1865, the Son of Rev. Algernon Sidney Grenfell, headmaster of Mostyn House School, and Jane Georgiana Hutchison.

Cape Chidley
Cape Chidley is a headland located on the eastern shore of Killiniq Island, Canada, at the northeastern tip of the Labrador Peninsula. Cape Chidley was named by English explorer John Davis on August 1, 1587, after his friend and fellow explorer John Chidley. On October 22, 1943, the landed just south of Cape Chidley and set up Weather Station Kurt to collect data about the weather. Originally, Cape Chidley was meant to be the site for a long-range radar station called "N-30." It was to fall within plans for the Pinetree Line, a series of radar stations across the 50th parallel. Supplies were moved to the site by ship during 1951–52, but in late 1952–early 1953 the site was moved to Resolution Island.The Pinetree LineThe Mystery of Site N-30 Oct, 2002 Location Sometimes spelled ''Cape Chudleigh'', Cape Chidley is located on the short boundary between the province of Newfoundland and Labrador and the territory of Nunavut on Killniq Island. It forms the northernmost point ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrodermal Activity
Electrodermal activity (EDA) is the property of the human body that causes continuous variation in the electrical characteristics of the skin. Historically, EDA has also been known as skin conductance, galvanic skin response (GSR), electrodermal response (EDR), psychogalvanic reflex (PGR), skin conductance response (SCR), sympathetic skin response (SSR) and skin conductance level (SCL). The long history of research into the active and passive electrical properties of the skin by a variety of disciplines has resulted in an excess of names, now standardized to electrodermal activity (EDA). The traditional theory of EDA holds that skin resistance varies with the state of sweat glands in the skin. Sweating is controlled by the sympathetic nervous system, and skin conductance is an indication of psychological or physiological arousal. If the sympathetic branch of the autonomic nervous system is highly aroused, then sweat gland activity also increases, which in turn increases skin condu ...

Birdsey Renshaw
Birdsey Renshaw (October 10, 1911, Middletown, Connecticut – November 23, 1948, Portland, Oregon) was an American electrophysiologist and neuroscientist. He is known for his 1941 discovery of the eponymous Renshaw cells and the Renshaw inhibition (recurrent inhibition), which is a negative feedback mechanism associated with the Renshaw cell action. Biography In 1936 he graduated with an M.D. from Harvard Medical School and then joined Alexander Forbes's neurophysiological research team in Harvard Medical School's physiology department. There he learned how to record cerebral action potentials using amplifiers and cathode-ray tubes. He developed microelectrodes from ultra-clean Pyrex pipettes and applied the microelectrodes to make extracellular recordings of action potentials found in the mammalian hippocampus and cortex. In 1938 he received his Ph.D. with thesis ''The Electrical Potentials Recorded in the Brain with Microelectrodes''. In 1938, after receiving his Ph.D.. he j ...

Edgar Adrian
Edgar Douglas Adrian, 1st Baron Adrian (30 November 1889 – 4 August 1977) was an English electrophysiologist and recipient of the 1932 Nobel Prize for Physiology, won jointly with Sir Charles Sherrington for work on the function of neurons. He provided experimental evidence for the all-or-none law of nerves. Biography Adrian was born in Hampstead, London, the youngest son of Alfred Douglas Adrian, legal adviser to the Local Government Board, and Flora Lavinia Barton. He was educated at Westminster School and then studied Natural Sciences at Trinity College, Cambridge, graduating in 1911. In 1913 he was elected to a fellowship of Trinity College on account of his research into the "all or none" law of nerves. After completing a medical degree (MB BCh) in 1915, he undertook clinical work at St Bartholomew's Hospital London during World War I, treating soldiers with nerve damage and nervous disorders such as shell shock.

Cybernetics
Cybernetics is a wide-ranging field concerned with circular causality, such as feedback, in regulatory and purposive systems. Cybernetics is named after an example of circular causal feedback, that of steering a ship, where the helmsperson maintains a steady course in a changing environment by adjusting their steering in continual response to the effect it is observed as having. Cybernetics is concerned with circular causal processes such as steering however they are embodied,Ashby, W. R. (1956). An introduction to cybernetics. London: Chapman & Hall, p. 1. including in ecological, technological, biological, cognitive, and social systems, and in the context of practical activities such as designing, learning, managing, conversation, and the practice of cybernetics itself. Cybernetics' transdisciplinary and "antidisciplinary" character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.

String Galvanometer
A string galvanometer is a sensitive fast-responding measuring instrument that uses a single fine filament of wire suspended in a strong magnetic field to measure small currents. In use, a strong light source is used to illuminate the fine filament, and the optical system magnifies the movement of the filament allowing it to be observed or recorded by photography. The principle of the string galvanometer remained in use for electrocardiograms until the advent of electronic vacuum-tube amplifiers in the 1920s. History Submarine cable telegraph systems of the late 19th century used a galvanometer to detect pulses of electric current, which could be observed and transcribed into a message. The speed at which pulses could be detected by the galvanometer was limited by its mechanical inertia, and by the inductance of the multi-turn coil used in the instrument. Clément Adair, a French engineer, replaced the coil with a much faster wire or "string" producing the first string galvanome ...
