James Olds
James Olds (May 30, 1922 – August 21, 1976) was an American psychologist who co-discovered the pleasure center of the brain with Peter Milner while he was a postdoctoral fellow at McGill University in 1954. He is considered to be one of the founders of modern neuroscience and received numerous distinctions ranging from election to the United States National Academy of Sciences to the Newcomb Cleveland Prize of the American Association for the Advancement of Science. Biography Early life and education Olds was born in Chicago, Illinois, and grew up in Nyack, New York. His father, Leland Olds, later became chairman of the Federal Power Commission during the 1940s. His grandfather George D. Olds was the ninth president of Amherst College. Olds attended college at a number of schools including St. John's College, Annapolis, and the University of Wisconsin but received his undergraduate B.A. from Amherst College in 1947. His undergraduate years were interrupted by military servi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleasure Center
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy). Reward is the attractive and motivational property of a stimulus that induces appetitive behavior, also known as approach behavior, and consummatory behavior. A rewarding stimulus has been described as "any stimulus, object, event, activity, or situation that has the potential to make us approach and consume it is by definition a reward". In operant conditioning, rewarding stimuli function as positive reinforcers; however, the converse statement also holds true: positive reinforcers are rewarding. The reward system motivates animals to approach stimuli or engage in behaviour that increases fit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Neuroscience
From the ancient Egyptian mummifications to 18th-century scientific research on "globules" and neurons, there is evidence of neuroscience practice throughout the early periods of history. The early civilizations lacked adequate means to obtain knowledge about the human brain. Their assumptions about the inner workings of the mind, therefore, were not accurate. Early views on the function of the brain regarded it to be a form of "cranial stuffing" of sorts. In ancient Egypt, from the late Middle Kingdom onwards, in preparation for mummification, the brain was regularly removed, for it was the heart that was assumed to be the seat of intelligence. According to Herodotus, during the first step of mummification: "The most perfect practice is to extract as much of the brain as possible with an iron hook, and what the hook cannot reach is mixed with drugs." Over the next five thousand years, this view came to be reversed; the brain is now known to be the seat of intelligence, although co ...

California Institute Of Technology
The California Institute of Technology (branded as Caltech) is a private research university in Pasadena, California, United States. The university is responsible for many modern scientific advancements and is among a small group of institutes of technology in the United States that are devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery Hale, Arthur Amos Noyes, and Robert Andrews Millikan in the early 20th century. The vocational and preparatory schools were disbanded and spun off in 1910, and the college assumed its present name in 1920. In 1934, Caltech was elected to the Association of American Universities, and the antecedents of NASA's Jet Propulsion Laboratory, which Caltech continues to manage and operate, were established between 1936 and 1943 under Theodore von Kármán.
