In medicine, a coma (from the Greek κῶμα koma, meaning deep sleep) is a state of unconsciousness, lasting more than six hours in which a person cannot be awakened, fails to respond normally to painful stimuli, light, sound, lacks a normal sleep-wake cycle and does not initiate voluntary actions.
Unconsciousness may occur as the result of traumatic brain injury, brain hypoxia (inadequate oxygen, possibly due to a brain infarction or cardiac arrest), severe intoxication with drugs that depress the activity of the central nervous system (e.g., alcohol and other hypnotic or sedative drugs), severe fatigue, pain, anaesthesia, and other causes.
The term "eternal oblivion" has been used in international treaties, such as in Article II of the Treaty of Westphalia 1648. [13] [14] It has also been used in legislation such as in the English Indemnity and Oblivion Act 1660, where the phrase used is "perpetual oblivion" (it appears in several of the articles in the act).
Modern dictionary definitions of the word consciousness evolved over several centuries and reflect a range of seemingly related meanings, with some differences that have been controversial, such as the distinction between inward awareness and perception of the physical world, or the distinction between conscious and unconscious, or the notion ...
Obliviousness may be described as going beyond a mere lack of some level of awareness, and becoming an act of repression of an awareness that should exist. [2] Although an unconscious person may similarly be unaware of things around them, obliviousness "implies not a cessation of all attention but only that directed outwardly", with the oblivious person's attention being "directed inwardly ...
Unconscious thought theory runs counter to decades of mainstream research on unconscious cognition (see Greenwald 1992 [4] for a review). Many of the attributes of unconscious thought according to UTT are drawn from research by George Miller and Guy Claxton on cognitive and social psychology, as well as from folk psychology; together these portray a formidable unconscious, possessing some ...
Conversely, unconscious states like deep sleep, coma, general anesthesia, and epileptic states of absence show a predominance of low frequency, high-amplitude and more regular voltages at less than 4Hz. Consciousness seems to be intrinsically associated with the thalamus and cortex, even if the extent to which this true is argued among scientists.
Unconscious cognition is the processing of perception, memory, learning, thought, and language without being aware of it. [1]The role of the unconscious mind on decision making is a topic greatly debated by neuroscientists, linguists, philosophers, and psychologists around the world.
