Hello, I am a mathematician and i have a personal theory of consciousness. Now, i DID read the rules for the forum, and i am aware that you guys don't want to be bothered with this, up to a point. However, i have isolated a key part of my theory in what are possibly satisfactory physical terms. I wish to ask just what is known about possible states of light (or E&M fields of other wavelengths) existing in the brain, i.e. in the biological tissue substrate of grey matter and white matter (or lower brain components). To the best of my knowledge it is not very well understood just what is possible here. Let me post a relevant link: http://www.bbc.co.uk/news/science-environment-21150047 . My theory would be that the visual field is literal light in the brain in the same physical locations as neurons which detect it AS the visual field. It is implied here that the literal light would be "generated" by other neural activity somehow ultimately originating from the retinas, etc. So the thing i want to ask about in this thread is: How much is known with as much certainty as possible (?) about existence, "stability", time evolution, etc of light in this "medium" (brain tissue). I am a mathematician. This means that 1) I am not a physicist so some help may be useful in understanding some concepts; 2) I should be able to go pretty far in a discussion which becomes mathematical. So, if i understand things properly, this thread (of which this is the Original Post) will need to discuss, possibly, optics, Quantum Mechanics, electromagnetic radiation and QFT. Can anyone say anything about this ... [question / issue] i am raising? I can provide more clarification, such as it is, if any responder has questions. I should mention that i have just joined this forum, and am not familiar with patterns of usage of this specific place on the net, if you will, so please bear with me if i seem a bit out of place.
