Jerome Lettvin
Jerome Ysroael Lettvin (February 23, 1920 – April 23, 2011), often known as Jerry Lettvin, was an American cognitive scientist, and Professor of Electrical and Bioengineering and Communications Physiology at the Massachusetts Institute of Technology (MIT). He is best known as the lead author of the paper, "What the Frog's Eye Tells the Frog's Brain" (1959), one of the most cited papers in the Science Citation Index. He wrote it along with Humberto Maturana, Warren McCulloch and Walter Pitts, and in the paper they gave special thanks and mention to Oliver Selfridge at MIT. Lettvin carried out neurophysiological studies in the spinal cord, made the first demonstration of "feature detectors" in the visual system, and studied information processing in the terminal branches of single axons. Around 1969, he originated the term "grandmother cell" to illustrate the logical inconsistency of the concept. Lettvin was also the author of many published articles on subjects varying from neu ...

Drug
A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. Consumption of drugs can be via insufflation (medicine), inhalation, drug injection, injection, smoking, ingestion, absorption (skin), absorption via a dermal patch, patch on the skin, suppository, or sublingual administration, dissolution under the tongue. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to pharmacotherapy, treat, cure, preventive healthcare, prevent, or medical diagnosis, diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a re ...

Psychedelic Drugs
Psychedelics are a subclass of Hallucinogen, hallucinogenic drugs whose primary effect is to trigger psychoactive drug, non-ordinary mental states (known as psychedelic experiences or "trips") and a perceived "expansion of consciousness". Also referred to as classic hallucinogens or serotonergic hallucinogens, the term ''psychedelic'' is sometimes used more broadly to include various other types of hallucinogens as well, such as those which are atypical or adjacent to psychedelia like Salvia divinorum, salvia and MDMA, respectively. Classic psychedelics generally cause specific psychological, psychedelic visuals, visual, and auditory changes, and oftentimes a substantially altered state of consciousness. They have had the largest influence on science and culture, and include mescaline, Lysergic acid diethylamide, LSD, psilocybin, and N,N-Dimethyltryptamine, DMT. There are a large number of both natural product, naturally occurring and synthetic compound, synthetic serotonergic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debates About Social Issues
Debate is a process that involves formal discourse, discussion, and oral addresses on a particular topic or collection of topics, often with a Discussion moderator, moderator and an audience. In a debate, arguments are put forward for opposing viewpoints. Historically, debates have occurred in public meetings, academic institutions, debate halls, English coffeehouses in the 17th and 18th centuries, coffeehouses, competitions, and Deliberative assembly, legislative assemblies. Debates have also been conducted for educational and recreational purposes, usually associated with educational establishments and debating societies. These debates emphasize logical consistency, factual accuracy, and emotional appeal to an audience. Modern competitive debate also includes rules for participants to discuss and decide upon the framework of the debate (how it will be judged). The term "debate" may also apply to a more continuous, inclusive, and less formalized process through which issues are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-drug
Substance misuse, also known as drug misuse or, in older vernacular, substance abuse, is the use of a drug in amounts or by methods that are harmful to the individual or others. It is a form of substance-related disorder, differing definitions of drug misuse are used in public health, medical, and criminal justice contexts. In some cases, criminal or anti-social behavior occurs when some persons are under the influence of a drug, and may result in long-term personality changes in individuals which may also occur. In addition to possible physical, social, and psychological harm, the use of some drugs may also lead to criminal penalties, although these vary widely depending on the local jurisdiction.. Drugs most often associated with this term include alcohol, amphetamines, barbiturates, benzodiazepines, cannabis, cocaine, hallucinogens, methaqualone, and opioids. The exact cause of substance abuse is sometimes clear, but there are two predominant theories: either a genetic pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Optic Nerve
In neuroanatomy, the optic nerve, also known as the second cranial nerve, cranial nerve II, or simply CN II, is a paired cranial nerve that transmits visual system, visual information from the retina to the brain. In humans, the optic nerve is derived from optic stalks during the seventh week of development and is composed of retinal ganglion cell axons and glial cells; it extends from the optic disc to the optic chiasma and continues as the optic tract to the lateral geniculate nucleus, Pretectal area, pretectal nuclei, and superior colliculus. Structure The optic nerve has been classified as the second of twelve paired cranial nerves, but it is technically a myelinated tract of the central nervous system, rather than a classical nerve of the peripheral nervous system because it is derived from an out-pouching of the diencephalon (optic stalks) during embryonic development. As a consequence, the fibers of the optic nerve are covered with myelin produced by oligodendrocytes, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Building 20
Building 20 (18 Vassar Street, Cambridge, Massachusetts) was a temporary timber structure hastily erected during World War II on the central campus of the Massachusetts Institute of Technology. Since it was always regarded as "temporary", it never received a formal name throughout its 55-year existence. (Many major buildings at MIT are known by their numbers regardless of how neoclassical or otherwise permanent they may be.) The three-floor structure originally housed the Radiation Laboratory (or "Rad Lab"), where fundamental advances were made in physical electronics, electromagnetic properties of matter, microwave physics, and microwave communication principles. It has been called one of America's "two prominent shrines of the triumph of science during the war" (along with the desert installation at Los Alamos National Laboratory, Los Alamos, where the atomic bomb was born). A former Rad Lab member said, "At one time, more than 20 percent of the physicists in the United States ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advocacy
Advocacy is an Action (philosophy), activity by an individual or advocacy group, group that aims to influence decision making, decisions within political, economic, and social institutions. Advocacy includes activities and publications to influence public policy, laws and budgets by using facts, their relationships, the media, and messaging to educate government officials and the public. Advocacy can include many activities that a person or organization undertakes, including media campaigns, public speaking, commissioning and publishing research. Lobbying (often by lobby groups) is a form of advocacy where a direct approach is made to legislators on a specific issue or specific piece of legislation. Research has started to address how advocacy groups in the United States and Canada are using social media to facilitate civic engagement and collective action. Forms There are several forms of advocacy, each representing a different approach in a way to initiate changes in the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conventionality
A convention influences a set of agreed, stipulated, or generally accepted standards, social norms, or other criteria, often taking the form of a custom. In physical sciences, numerical values (such as constants, quantities, or scales of measurement) are called conventional if they do not represent a measured property of nature, but originate in a convention, for example an average of many measurements, agreed between the scientists working with these values. General A convention is a selection from among two or more alternatives, where the rule or alternative is agreed upon among participants. Often the word refers to unwritten customs shared throughout a community. For instance, it is conventional in many societies that strangers being introduced shake hands. Some conventions are explicitly legislated; for example, it is conventional in the United States and in Germany that motorists drive on the right side of the road, whereas in Australia, New Zealand, Japan, Nepal, India a ...
