Forebrain neural activities can correlate with sense qualities {neuronal correlates of consciousness}| (NCC) [Alauddin et al., 2003] [Calvin, 1996] [Calvin, 1996] [Calvin, 1998] [Cotterill, 1998] [Changeux, 1983] [Crick and Koch, 1992] [Crick and Koch, 2003] [Crick, 1979] [Crick, 1994] [Dehaene and Changeux, 2004] [Dehaene and Naccache, 2001] [Dehaene, 2001] [Dehaene et al., 2003] [Dragunow and Faull, 1989] [Fried et al., 1998] [Graziano et al., 2002] [Greenfield, 1995] [Greenfield, 2000] [Han et al., 2003] [Jasper, 1998] [Koch and Davis, 1994] [Koch, 2004] [Lechner et al., 2002] [Li et al., 2002] [Llinás et al., 1998] [Slimko et al., 2002] [Taylor, 1998] [Yamamoto et al., 2003].
brain processes
Consciousness is not about brain processes, because they are at low level. Algorithm high-level code must use low-level code for processor. Brain processes do not yet reveal higher code or algorithm.
brain regions
Consciousness can be a whole-brain, many-connected-region, few-connected-regions, or one-brain-region property [Chalmers, 2000] [Metzinger, 2000] [Mollon and Sharpe, 1983] [O'Regan and Noë, 2001] [Pessoa et al., 1998] [Teller, 1984] [Teller and Pugh, 1983].
Perhaps, brain has sets of different neurons, whose information, interactions, or processing is necessary and/or sufficient for consciousness aspects.
Awakeness depends on nuclei below cortex and thalamus that excite, or remove inhibition from, cortex and thalamus non-specifically, but these nuclei do not directly make sense qualities.
Sense qualities depend on cortex and thalamus, but cortex and thalamus regions project to local or distant cortex and thalamus locations, so no region relates to sense qualities.
complexity
Many non-conscious processes involve complex computations, and brain can learn complex non-conscious processes. Many widespread brain processes have no association with consciousness. Both unconscious and conscious processes involve neurons with high firing rates and/or large chemical changes.
feedback
Perhaps, consciousness requires feedback in brain pathways. Illusions can switch between two different sense qualities or perceptions about same figure or image. Perception depends on memory and thalamocortical feedback.
iteration
Perhaps, experience involves iteration, but repetition delays processing and limits discrimination.
Probably, experience does not use iteration, repetition, waves, vibrations, oscillations, or anything periodic, because such processing limits information.
mind requirements
Consciousness requires information from objects and events outside brain, information transfer from receptors to processors, and effector controls. Information channels from objects and events to brain to effectors must have enough information capacity and speed. Channels have reverse channels to provide feedback and synchronization. Information codes must express all physical relations.
physiology
Perhaps, cell membrane polarizations and depolarizations; chemical concentration changes from manufacture, destruction, or transfer; or cell structure changes at synapses or dendrites have biochemical and biophysical effects that cause experience. Perhaps, brain-pathway cellular-connection changes cause experience. Consciousness-causing activity must last long enough to allow integration and be short enough to prevent signal overlap. Neuron activity affects other neurons, so correlations can be widespread and indirect.
similar neurons
Perhaps, brain has "consciousness neurons" that have similar ion channels, shapes, receptors, axons, synapses, and/or biochemistry. Perhaps, some neuron feature is necessary and/or sufficient for consciousness aspects. However, no neuron properties or events, including connections, directly relate to sense qualities.
