Restricted Environmental Stimulation Technique
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, and depression. A related phenomenon is perceptual deprivation, also called the Ganzfeld effect. In this case a constant uniform stimulus is used instead of attempting to remove the stimu ...

Stimulus (physiology)
In physiology, a stimulus is a change in a living thing's internal or external environment. This change can be detected by an organism or organ using sensitivity, and leads to a physiological reaction. Sensory receptors can receive stimuli 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 the central nervous system (CNS), where it is integrated and a decision on how to ...

Phenomenon
A phenomenon ( phenomena), sometimes spelled phaenomenon, is an observable Event (philosophy), event. The term came into its modern Philosophy, 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 Philosophy, ancient Greek Pyrrhonism, 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, unusual or notable event. 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. ...

Jan Te Nijenhuis
Jan te Nijenhuis is a Dutch psychologist. He is a lecturer of psychology at the University of Amsterdam, known for his research on human intelligence.

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. T ...

Cortisol
Cortisol is a steroid hormone in the glucocorticoid class of hormones and a stress hormone. When used as medication, it is known as hydrocortisone. Cortisol is produced in many animals, mainly by the ''zona fasciculata'' of the adrenal cortex in an adrenal gland. In other tissues, it is produced in lower quantities. By a Circadian rhythm, diurnal cycle, cortisol is released and increases in response to Stress (biology), stress and a low Blood sugar, blood-glucose concentration. It functions to increase blood sugar through gluconeogenesis, suppress the immune system, and aid in the metabolism of calories. It also decreases bone formation. These stated functions are carried out by cortisol binding to glucocorticoid or mineralocorticoid receptors inside a cell, which then bind to DNA to affect gene expression. Health effects Metabolic response Metabolism of glucose Cortisol plays a crucial role in regulating glucose metabolism and promotes gluconeogenesis (glucose synthes ...

Epsom Salts
Epsomite, Epsom salt, or magnesium sulfate heptahydrate, is a hydrous magnesium sulfate mineral with formula . Physical properties Epsomite crystallizes in the orthorhombic system. The normal form is as massive encrustations, while acicular or fibrous crystals are rarely found. It is colorless to white with tints of yellow, green and pink. It is a soft mineral with variable Mohs hardness around 2.0~2.5, and it has a low specific gravity It is readily soluble in water, and absorbs water from the air. It converts to hexahydrate with the loss of one water molecule and a switch to monoclinic structure. The epsomite group includes solid solution series with morenosite (·) and goslarite (·). Etymology It was first systematically described in 1806 for an occurrence near Epsom, Surrey, England, after which it was named. It has been also referred to as "cave cotton" when in its fibrous form. Occurrence Epsomite forms as encrustations or efflorescences on limestone cave ...

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 The Universal Declaration of Human Rights (UDHR) is an international document adopted by the United Nations General Assembly that enshrines the Human rights, rights and freedoms of all human beings. Drafted by a UN Drafting of the Universal D ..., 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 a distinction between torture and CIDT is maintained from a legal point of view, medical and psychological studies have found that this distinction is virtually nonexistent from a psychological point of view, and that people subjected to CIDT experience the same consequences as survivors of torture. Based on this research, some practitioners have recommended a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Five Techniques
The five techniques, also known as deep interrogation, are a group of interrogation methods developed by the United Kingdom during the 20th century and are currently regarded as a form of torture. Originally developed by British forces in a variety of 20th-century conflicts, they are most notable for being applied to detainees in Northern Ireland during the Troubles. The five collective methods are 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 of people ostensibly suspected of involvement with the Provisional Irish Republican Army (IRA). Out of those arrested, fourteen were selected not for any suspected involvement but purely on the basis of physical condition and subjected to a programme of "deep interrogation" using the five techniques. This took place at Shackleton Barracks, a secret interro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
