Models of consciousness
Models of Consciousness are used to illustrate and aid in understanding and explaining distinctive aspects consciousness. Sometimes the models are labeled 'theories of consciousness'.
Eight-Circuit Model of Consciousness
Timothy Leary introduced[1] and Robert Anton Wilson and Antero Alli elaborated the Eight-circuit model of consciousness as hypothesis that "suggested eight periods [circuits] and twenty-four stages of neurological evolution".
Multiple drafts model
Daniel Dennett proposed a physicalist, information processing based multiple drafts model of consciousness described more fully in his 1991 book, Consciousness Explained.
Dehaene–Changeux model
The Dehaene–Changeux model (DCM), also known as the global neuronal workspace or the global cognitive workspace model is a computer model of the neural correlates of consciousness programmed as a neural network. Stanislas Dehaene and Jean-Pierre Changeux introduced this model in 1986.[2] It is associated with Bernard Baars's Global workspace theory for consciousness.
Clouding of consciousness
Clouding of consciousness, also known as brain fog or mental fog, is a term used in medicine denoting an abnormality in the regulation of the overall level of consciousness that is mild and less severe than a delirium[3]. It is part of an overall model where there's regulation of the "overall level" of the consciousness of the brain and aspects responsible for "arousal" or "wakefulness" and awareness of oneself and of the environment[4].
Electromagnetic theories of consciousness
Electromagnetic theories of consciousness propose that consciousness can be understood as an electromagnetic phenomenon that occurs when a brain produces an electromagnetic field with specific characteristics.[5] [6] Some electromagnetic theories are also quantum mind theories of consciousness; examples include quantum brain dynamics (QBD).[7]
Orchestrated objective reduction
Orchestrated objective reduction (Orch-OR) model is based on the hypothesis that consciousness in the brain originates from quantum processes inside neurons, rather than from connections between neurons (the conventional view). The mechanism is held to be associated with molecular structures called microtubules. The hypothesis was advanced by Roger Penrose and Stuart Hameroff and has been the subject of extensive debate[8], [9]
Functionalism (philosophy of mind)
Functionalism is a view in the theory of the mind. It states that mental states (beliefs, desires, being in pain, etc.) are constituted solely by their functional role – that is, they have causal relations to other mental states, numerous sensory inputs, and behavioral outputs.
Sociology of human consciousness
Sociology of human consciousness uses the theories and methodology of sociology to explain human consciousness. The theory and its models emphasize the importance of language, collective representations, self-conceptions, and self-reflectivity. It argues that the shape and feel of human consciousness is heavily social.
