Brain/Chalmers: how could a physical system such as a brain also be an experiencer? Why should there be something like how it is to be such a system?
Brain/Neurobiology/Neurophysiology/Awareness/Explanation/Chalmers: There are approaches by Francis Crick and Christof Koch (1990) on 40 Hertz oscillation...
...and by Gerald Edelman (1989) who explain the phenomenal side of consciousness just as little as cognitive models (see Cognition/Chalmers).
Brain state/Chalmers: what are the physical correlations to conscious experiences?
Crick and Koch (1990): Thesis: 40 Hertz oscillations in the cortex are the neural correlates of the experience.
Baars (1988): thesis: a global "work space" is the basis for information processing of experiences in which the contents correspond directly to the contents of the work space.
Farah (1994) Thesis: Consciousness is associated with high-quality representations in the brain.
Libet (1993) Thesis: Consciousness is associated with neuronal activities that last long enough, with the minimum duration being about 500 milliseconds._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
