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 ...

Prospect Place
Prospect Place, also known as Trinway Mansion and Prospect Place Mansion, is a 29-room mansion built by abolitionist George Willison Adams (G. W. Adams) in Trinway, Ohio, just north of Dresden in 1856. Today, it is the home of the non-profit G. W. Adams Educational Center, Inc. The mansion is listed on the National Register of Historic Places and the Ohio Underground Railroad Association's list of Underground Railroad sites. This home featured many new and, for the time, revolutionary innovations. It had indoor plumbing which included a copper tank cistern on the second floor which pressurized water throughout the house. Two coal stoves had copper tanks (under pressure from the cistern system) which heated water and allowed the home to have both hot and cold running water service. This is the second house to stand on the same foundation. The first house was destroyed by an arson-related fire shortly after its completion. The mansion was rebuilt after the fire, with moder ...

Harvard Medical School Alumni
Harvard University is a private Ivy League research university in Cambridge, Massachusetts. Founded in 1636 as Harvard College and named for its first benefactor, the Puritan clergyman John Harvard, it is the oldest institution of higher learning in the United States and one of the most prestigious and highly ranked universities in the world. The university is composed of ten academic faculties plus Harvard Radcliffe Institute. The Faculty of Arts and Sciences offers study in a wide range of undergraduate and graduate academic disciplines, and other faculties offer only graduate degrees, including professional degrees. Harvard has three main campuses: the Cambridge campus centered on Harvard Yard; an adjoining campus immediately across Charles River in the Allston neighborhood of Boston; and the medical campus in Boston's Longwood Medical Area. Harvard's endowment is valued at $50.9 billion, making it the wealthiest academic institution in the world. Endowment inco ...

Electrophysiologists
Electrophysiology (from Greek , ''ēlektron'', "amber" etymology of "electron"">Electron#Etymology">etymology of "electron" , ''physis'', "nature, origin"; and , '' -logia'') is the branch of physiology that studies the electrical properties of biological cells and tissues. It involves measurements of voltage changes or electric current or manipulations on a wide variety of scales from single ion channel proteins to whole organs like the heart. In neuroscience, it includes measurements of the electrical activity of neurons, and, in particular, action potential activity. Recordings of large-scale electric signals from the nervous system, such as electroencephalography, may also be referred to as electrophysiological recordings. They are useful for electrodiagnosis and monitoring. Definition and scope Classical electrophysiological techniques Principle and mechanisms Electrophysiology is the branch of physiology that pertains broadly to the flow of ions (ion current) in biologi ...

Journal Of Neurophysiology
The ''Journal of Neurophysiology'' is a monthly peer-reviewed scientific journal established in 1938. It is published by the American Physiological Society with Jan "Nino" Ramirez as its editor-in-chief. Ramirez is the Director for the Center for Integrative Brain Research at the University of Washington. The ''Journal of Neurophysiology'' publishes original articles on the function of the nervous system. All levels of function are included, from membrane biophysics to cell biology to systems neuroscience and the experimental analysis of behavior. Experimental approaches include molecular neurobiology, cell culture and slice preparations, membrane physiology, developmental neurobiology, functional neuroanatomy, neurochemistry, neuropharmacology, systems electrophysiology, imaging and mapping techniques, and behavioral analysis.

Foreign Policy Association
The Foreign Policy Association (formerly known as the League of Free Nations Association) is a non-profit organization founded in 1918 dedicated to inspiring the American public to learn more about the world. The Foreign Policy Association aims to spread global awareness and understanding of foreign policy issues. The organization's current President & CEO is Noel V. Lateef. History The FPA was founded in 1918 as the "League of Free Nations Association". Under the chairmanship of journalist Paul Underwood Kellogg, it was formed by 41 Americans to support US President Woodrow Wilson's efforts to achieve a just peace, with his speech and proposal of the Fourteen Points, which included the idea of a world organization, later to be called the League of Nations. It was also to increase support for United States membership in the world body that was then being discussed and laid out in the Versailles Treaty and the Paris Peace Conference, 1919, with the "Big Four" representatives dominat ...

Peace Corps
The Peace Corps is an independent agency and program of the United States government that trains and deploys volunteers to provide international development assistance. It was established in March 1961 by an executive order of President John F. Kennedy Executive Order 10924 and authorized by Congress the following September by the Peace Corps Act. Kennedy first publicly proposed the Peace Corps during his 1960 presidential campaign as a means to improve America's global image and leadership in the Cold War; he cited the Soviet Union's deployment of skilled citizens "abroad in the service of world communism" and argued the U.S. must do the same to advance values such as democracy and liberty. The Peace Corps was formally established within three months of Kennedy's presidency, garnering both bipartisan congressional support and popular support, particularly among recent university graduates. The official goal of the Peace Corps is to assist developing countries by providing skil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
