Consciousness: Brain
built 644 days ago
Consciousness-based education enlivens total brain functioning of the student. It creates fully developed students who learn better and more easily, memorise more quickly and get better results. They are ... happier, healthier, more tolerant, insightful students who can be more successful in their professional and personal lives.

The core of his theory of consciousness is the "multiple drafts" model. In the multiple drafts model consciousness is not a unitary process but rather a distributed one (just as a novel in preparation may exist in multiple drafts at any one time and is only afterwards "finalised"). Sequential timing of events breaks down at small (millisecond) time scales within the brain, and the events that make up consciousness cannot be ordered. In short there is no central place in the brain/mind where everything is presented and decisions are made (the fallacy of the "Cartesian Theatre"). The evidence for this view of consciousness is a whole series of results from experiments in cognitive psychology and neuroscience.

Loss of consciousness ... occurs in other conditions, such as general (tonic-clonic) epileptic seizures, in general anaesthesia, maybe even in deep (slow-wave) sleep. At present, the best-supported hypotheses about such cases of loss of consciousness (or loss of time resolution) focus on the need for 1) a widespread cortical network, including particularly the frontal, parietal and temporal cortices, and 2) cooperation between the deep layers of the brain, especially the thalamus, and the upper layers, the cortex. Such hypotheses go under the common term "globalist theories" of consciousness, due to the claim for a widespread, global network necessary for consciousness to interact with non-mental reality in the first place.

To anyone interested in the nature of mind or consciousness the evidence for life after death should be of compelling interest. If it could be shown that consciousness even briefly could function outside the brain, or after the brain was destroyed by death, there would be important implications for psychology, politics, medicine, religion, and psychotherapy. Evidence making such claims is mainly ignored by mainstream science today, but there is quite a bit and much of it cannot be easily explained away.

It is sometimes held that consciousness emerges from the complexity of brain processing (see for instance the Multiple Drafts Model of consciousness). The general label 'emergence' applies to new phenomena that emerge from a physical basis without the connection between the two explicitly specified.

Is consciousness a property of the entire brain — does it ‘emerge’ when the brain reaches a certain level of complexity? Or are only some parts of the brain conscious? (After all, if we argue that only brains and not other organs are conscious, why not imagine that only some parts of the brain are involved?) Indeed, neurological evidence suggests that we are unconscious of most of the activity in our brains — not just the below-stairs business of running the heart, digestion, posture, and so on, but ... the pre-perceptual processing of information from the senses, and the complex task of selecting and controlling the individual muscles that carry out actions.
