Sensory Deprivation
Sensory deprivation or perceptual isolation is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and the ability to know which way is down. Sensory deprivation has been used in various alternative medicines and in psychological experiments (e.g. with an isolation tank). When deprived of sensation, the brain attempts to restore sensation in the form of hallucinations. Short-term sessions of sensory deprivation are described as relaxing and conducive to meditation; however, extended or forced sensory deprivation can result in extreme anxiety, hallucinations, bizarre thoughts, temporary senselessness, and depression A related phenomenon is perceptual deprivation, also called the Ganzfeld effect. In this case a constant uniform stimulus is used instead of att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stimulus (physiology)
In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment. The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity (excitability). Sensory receptors can receive information from outside the body, as in touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors. When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction. An internal stimulus is often the first component of a homeostatic control system. External stimuli are capable of producing systemic responses throughout the body, as in the fight-or-flight response. In order for a stimulus to be detected with high probability, its level of strength must exceed the absolute threshold; if a signal does reach threshold, the information is transmitted to ...

Phenomenon
A phenomenon ( : phenomena) is an observable event. The term came into its modern philosophical usage through Immanuel Kant, who contrasted it with the noumenon, which ''cannot'' be directly observed. Kant was heavily influenced by Gottfried Wilhelm Leibniz in this part of his philosophy, in which phenomenon and noumenon serve as interrelated technical terms. Far predating this, the ancient Greek Pyrrhonist philosopher Sextus Empiricus also used ''phenomenon'' and ''noumenon'' as interrelated technical terms. Common usage In popular usage, a ''phenomenon'' often refers to an extraordinary event. The term is most commonly used to refer to occurrences that at first defy explanation or baffle the observer. According to the ''Dictionary of Visual Discourse'':In ordinary language 'phenomenon/phenomena' refer to any occurrence worthy of note and investigation, typically an untoward or unusual event, person or fact that is of special significance or otherwise notable.

Hemodynamics
Hemodynamics or haemodynamics are the dynamics of blood flow. The circulatory system is controlled by homeostatic mechanisms of autoregulation, just as hydraulic circuits are controlled by control systems. The hemodynamic response continuously monitors and adjusts to conditions in the body and its environment. Hemodynamics explains the physical laws that govern the flow of blood in the blood vessels. Blood flow ensures the transportation of nutrients, hormones, metabolic waste products, oxygen, and carbon dioxide throughout the body to maintain cell-level metabolism, the regulation of the pH, osmotic pressure and temperature of the whole body, and the protection from microbial and mechanical harm. Blood is a non-Newtonian fluid, and is most efficiently studied using rheology rather than hydrodynamics. Because blood vessels are not rigid tubes, classic hydrodynamics and fluids mechanics based on the use of classical viscometers are not capable of explaining haemodynamics. The st ...

Cortisol
Cortisol is a steroid hormone, in the glucocorticoid class of hormones. When used as a medication, it is known as hydrocortisone. It is produced in many animals, mainly by the ''zona fasciculata'' of the adrenal cortex in the adrenal gland. It is produced in other tissues in lower quantities. It is released with a diurnal cycle and its release is increased in response to stress and low blood-glucose concentration. It functions to increase blood sugar through gluconeogenesis, to suppress the immune system, and to aid in the metabolism of fat, protein, and carbohydrates. It also decreases bone formation. Many of these functions are carried out by cortisol binding to glucocorticoid or mineralocorticoid receptors inside the cell, which then bind to DNA to impact gene expression. Health effects Metabolic response Metabolism of glucose In general, cortisol stimulates gluconeogenesis (the synthesis of 'new' glucose from non-carbohydrate sources, which occurs mainly in th ...

Epsom Salts
Magnesium sulfate or magnesium sulphate (in English-speaking countries other than the US) is a chemical compound, a salt with the formula , consisting of magnesium cations (20.19% by mass) and sulfate anions . It is a white crystalline solid, soluble in water but not in ethanol. Magnesium sulfate is usually encountered in the form of a hydrate , for various values of ''n'' between 1 and 11. The most common is the heptahydrate , known as Epsom salt, which is a household chemical with many traditional uses, including bath salts. The main use of magnesium sulfate is in agriculture, to correct soils deficient in magnesium (an essential plant nutrient because of the role of magnesium in chlorophyll and photosynthesis). The monohydrate is favored for this use; by the mid 1970s, its production was 2.3 million tons per year. The anhydrous form and several hydrates occur in nature as minerals, and the salt is a significant component of the water from some springs. Hydrates Magnesium s ...

Flotation Tank SMC
Flotation (also spelled floatation) involves phenomena related to the relative buoyancy of objects. The term may also refer to: *Flotation (archaeology), a method for recovering very small artefacts from excavated sediments *Flotation (shares), an initial public offering of stocks or shares in a company *Flotation, any material added to the hull of a watercraft to keep the hull afloat *Flotation, the ability (as of a tire or snowshoes) to stay on the surface of soft ground or snow *"Floatation", a 1990 electronic music song by The Grid *Flotation process, in process engineering, a method for the separation of mixtures **Dissolved air flotation (DAF), a water treatment process **Froth flotation, a process for separating hydrophobic from hydrophilic materials **Induced gas flotation, a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids *Flotation therapy, a technique whereby users 'float' in an isolation ta ...

Guantanamo Bay Detention Camp
The Guantanamo Bay detention camp ( es, Centro de detención de la bahía de Guantánamo) is a United States military prison located within Guantanamo Bay Naval Base, also referred to as Guantánamo, GTMO, and Gitmo (), on the coast of Guantánamo Bay in Cuba. Of the roughly 780 people detained there since January 2002 when the military prison first opened after the September 11 attacks, 735 have been transferred elsewhere, 35 remain there, and 9 have died while in custody. The camp was established by U.S. President George W. Bush's administration in 2002 during the War on Terror following the September 11, 2001 attacks. Indefinite detention without trial led the operations of this camp to be considered a major breach of human rights by Amnesty International, and a violation of the Due Process Clause of the Fifth and Fourteenth amendments of the United States Constitution by the Center for Constitutional Rights.

Inhuman And Degrading Treatment
Cruel, inhuman or degrading treatment (CIDT) is treatment of persons which is contrary to human rights or dignity, but is not classified as torture. It is forbidden by the Universal Declaration of Human Rights, Article 3 of the European Convention on Human Rights, the United Nations Convention against Torture and the International Covenant on Civil and Political Rights. Although the distinction between torture and CIDT is maintained from a legal point of view, medical and psychological studies have found that it does not exist from the psychological point of view, and people subjected to CIDT will experience the same consequences as survivors of torture. Based on this research, some practitioners have recommended abolishing the distinction. Inhuman treatment The Equality and Human Rights Commission defines inhuman treatment as: * serious physical assault * psychological interrogation * cruel detention conditions or restraints * physical or psychological abuse in a healthcare sett ...

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Five Techniques
The five techniques (also known as Deep-Interrogation) are illegal interrogation methods which were originally developed by the British military in other operational theatres and then applied to detainees during the Troubles in Northern Ireland. They have been defined as prolonged wall-standing, hooding, subjection to noise, deprivation of sleep, and deprivation of food and drink. They were first used in Northern Ireland in 1971 as part of Operation Demetrius – the mass arrest and internment (imprisonment without trial) of people suspected of involvement with the Provisional Irish Republican Army (IRA). Out of those arrested, fourteen were subjected to a programme of "deep interrogation" using the five techniques. This took place at Shackleton Barracks, a secret interrogation centre in Northern Ireland. For seven days, when not being interrogated, the detainees were kept hooded and handcuffed in a cold cell and subjected to a continuous loud hissing noise. Here they were for ...
