GWT analogizes the mind to a theater, with conscious thought being like material illuminated on the main stage. The brain contains many specialized processes or modules that operate in parallel, much of which is unconscious. Attention acts as a spotlight, bringing some of this unconscious activity into conscious awareness on the global workspace.
There are theories proposed of quantum consciousness based on quantum mechanics. [7] There is an apparent redundancy and parallelism in neural networks so, while activity in one group of neurons may correlate with a percept in one case, a different population may mediate a related percept if the former population is lost or inactivated.
Olaf Blanke's studies on out-of-body experiences explore an example where conscious experience changes while external stimuli stay the same. 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.
Sufficiently more evolved is the second layer of Damasio's theory, Core Consciousness. This emergent process occurs when an organism becomes consciously aware of feelings associated with changes occurring to its internal bodily state; it is able to recognize that its thoughts are its own, and that they are formulated in its own perspective.

The hope is to find that activity in a particular part of the brain, or a particular pattern of global brain activity, which will be strongly predictive of conscious awareness. Several brain imaging techniques, such as EEG and fMRI, have been used for physical measures of brain activity in these studies. [97]
TWO EARLIER LANDMARK STUDIES also support a quantum perspective on consciousness. Both involved experiments shining light particles into microtubules and observing that the signal did not degrade.
Phi; the symbol used for integrated information. Integrated information theory (IIT) proposes a mathematical model for the consciousness of a system. It comprises a framework ultimately intended to explain why some physical systems (such as human brains) are conscious, [1] and to be capable of providing a concrete inference about whether any physical system is conscious, to what degree, and ...
Dreaming is thus a virtual reality experience with a remarkably predictive simulation of external reality. Lucid dreamers may experience primary consciousness (the dream) and secondary consciousness (the waking) separately but simultaneously. Moreover, primary consciousness has recently been proposed by us to be characteristic of dreaming.
