  Consciousness - Free Encyclopedia of Thelema
Consciousness is a quality of the mind generally regarded to comprise qualities such as subjectivity, self-awareness, sentience, sapience, and the ability to perceive the relationship between oneself and one's environment.
In common parlance, consciousness denotes being awake and responsive to one's environment; this contrasts with being asleep or being in a coma.
Modern investigations into and discoveries about consciousness are based on psychological statistical studies and case studies of consciousness states and the deficits caused by lesions, stroke, injury, or surgery that disrupt the normal functioning of human senses and cognition.

 Electromagnetic theories of consciousness - Wikipedia, the free encyclopedia
The electromagnetic theory of consciousness is a theory that says the electromagnetic field generated by the brain (known for a long time, and measured by EEG's) is the actual carrier of conscious experience.
This theory was initially proposed by scientists such as Johnjoe McFadden, Susan Pockett and E. Roy John (For the recent account see Andrew and Alexander Fingelkurts).
Locating consciousness in the brain's EM field, rather than the neurons, has the advantage that it neatly accounts for how information located in millions of neurons scattered throughout the brain can be unified into a single conscious experience (sometimes called the binding problem): the information is unified in the EM field.

 Consciousness
Theories that seek to explain behaviour are an everyday part of neuroscience, some of these theories of access consciousness, such as Edelman's theory, contentiously identify phenomenal consciousness with reflex events in the brain.
Theories that seek to explain phenomenal consciousness directly, such as Space-time theories of consciousness and Electromagnetic theories of consciousness, have been available for almost a century, but have not yet been confirmed by experiment.
Theories that attempt to explain the QM measurement problem include Pribram and Bohm's Holonomic brain theory, Hameroff and Penrose's Orch-OR theory, Spin-Mediated Consciousness Theory and the Many-minds interpretation.

 Consciousness (Stanford Encyclopedia of Philosophy)
Although the words “conscious” and “conscience” are used quite differently today, it is likely that the Reformation emphasis on the latter as an inner source of truth played some role in the inward turn so characteristic of the modern reflective view of self.
Conscious organisms obviously differ in the extent to which they constitute a unified and coherent self, and they likely differ accordingly in the sort or degree of perspectival focus they embody in their respective forms of experience (Lorenz 1977).
Our conscious mental states seem to have their meanings intrinsically or from the inside just by being what they are in themselves, by contrast with many externalist theories of mental content that ground meaning in causal, counterfactual or informational relations between bearers of intentionality and their semantic or referential objects.

 Hypotheses of consciousness and spacetime - Wikipedia, the free encyclopedia
These theories should properly be called hypotheses and sometimes make specific predictions, and so their proponents assert that they should be considered as protoscience rather than pseudoscience.
Only the consciousness that passes on in one portion of this world experiences the detached piece which comes to meet it and passes behind it, as history, that is, as a process that is going forward in time and takes place in space".
The possibility that conscious experience occupies a short period of time (the specious present) would mean that it can include movements and short words; these would not seem to be possible in a presentist interpretation of experience.

 Consciousness [Internet Encyclopedia of Philosophy]
Any theory which attempts to explain consciousness in terms of higher-order states is known as a higher-order (HO) theory of consciousness.
HO theories, thus, attempt to explain consciousness in mentalistic terms, that is, by reference to such notions as “thoughts” and “awareness.” Conscious mental states arise when two unconscious mental states are related in a certain specific way; namely, that one of them (the HOR) is directed at the other (M).
Conscious experience seems to be “unified” in an important sense; this crucial feature of consciousness played an important role in the philosophy of Kant who argued that unified conscious experience must be the product of the (presupposed) synthesizing work of the mind.

Because humans express their conscious states using language, it is tempting to equate language abilities and consciousness.
The Hard problem of consciousness is how to explain a state of phenomenal Consciousness in terms of its neurological basis (Chalmers 1996).
Naive and Direct Realists believe that access Consciousness is all that needs to be known about Consciousness because they regard phenomenal Consciousness as the world itself.

 Wired News: Consciousness Based on Wireless?
Human consciousness is actually wireless communication between the cells of your brain, according to a professor of molecular genetics at the University of Surrey in Great Britain.
In this way, the electromagnetic field works as a sort of wireless processor, combining the most important information from the hard wiring of the brain into a wireless signal, which is then transmitted back to the brain as conscious thought.
Scientific study of consciousness has only recently begun to gain acceptance as a legitimate scientific discipline, and some think field theories like McFadden's are pseudo-science that threaten their hard-worn legitimacy.

Orch OR (“Orchestrated Objective Reduction”) is a theory of consciousness put forth in the mid-1990s by British physicist Sir Roger Penrose and American anesthesiologist Stuart Hameroff.
Whereas most theories assume consciousness emerges from complex computation at the level of synapses among brain neurons, Orch OR involves a specific form of quantum computation which underlies these neuronal synaptic activities.
However because dendrites are apparently more involved in consciousness than axons (which contain many microtubules), and because not all microtubules in a given dendrite are likely to be involved at any one time, an estimate of, say, 10 percent involvement gives 200,000 neurons involved in consciousness every 25 msec.

 The Panda's Thumb
While a thought-provoking idea, Geoffroy lacked the substantial evidence to make a persuasive case—he had to rely on fairly superficial similarities to argue for something that, to those familiar with the details, appeared contrary to reason and was therefore unconvincing.
Evolutionary biology has changed that — the identification of relationships and the theory of common descent has made it unreasonable to argue against origins in a common ancestor — but that difficult problem of homology remains.
Seville’s other pop culture contribution with pitch-shifting was The Chipmunks, the musical phenomenon that later became a cartoon franchise, with characters Alvin, Simon, and Theodore as the chipmunks and Seville as songwriter/manager/father figure.
