  2. Minimally conscious state - Wikipedia

    en.wikipedia.org/wiki/Minimally_conscious_state

    Because minimally conscious state is a relatively new criterion for diagnosis, there are very few functional imaging studies of patients with this condition. Preliminary data has shown that overall cerebral metabolism is less than in those with conscious awareness (20–40% of normal [3]) and is slightly higher but comparable to those in vegetative states.

  3. Orchestrated objective reduction - Wikipedia

    en.wikipedia.org/wiki/Orchestrated_objective...

    Orchestrated objective reduction (Orch OR) is a theory postulating that consciousness originates at the quantum level inside neurons (rather than being a product of neural connections). The mechanism is held to be a quantum process called objective reduction that is orchestrated by cellular structures called microtubules.

  4. Neural correlates of consciousness - Wikipedia

    en.wikipedia.org/wiki/Neural_correlates_of...

    A science of consciousness must explain the exact relationship between subjective mental states and brain states, the nature of the relationship between the conscious mind and the electrochemical interactions in the body (mind–body problem). Progress in neuropsychology and neurophilosophy has come from focusing on the body rather than the mind.

  5. Consciousness and the Brain - Wikipedia

    en.wikipedia.org/wiki/Consciousness_and_the_Brain

    In Ch. 4, Dehaene notes that correlates of consciousness are actually insufficient, because many things can correlate with conscious perception, including even brain states prior to presentation of a stimulus. Dehaene is most interested in neural signatures of consciousness that represent the consciousness brain processing itself. (p.

  6. Models of consciousness - Wikipedia

    en.wikipedia.org/wiki/Models_of_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.

  7. Global workspace theory - Wikipedia

    en.wikipedia.org/wiki/Global_Workspace_Theory

    J. W. Dalton has criticized the global workspace theory on the grounds that it provides, at best, an account of the cognitive function of consciousness, and fails even to address the deeper problem of its nature, of what consciousness is, and of how any mental process whatsoever can be conscious: the hard problem of consciousness. [14] A. C.

    Consciousness: How can consciousness be defined? What is the neural basis of subjective experience, cognition, wakefulness, alertness, arousal, and attention? Binding problem: How exactly is it that objects, background, and abstract or emotional features are combined into a single experience? What is the neural basis of self?

  9. Holonomic brain theory - Wikipedia

    en.wikipedia.org/wiki/Holonomic_brain_theory

    Holonomic brain theory is a branch of neuroscience investigating the idea that consciousness is formed by quantum effects in or between brain cells. Holonomic refers to representations in a Hilbert phase space defined by both spectral and space-time coordinates. [1]
