is consciousness a brain chemical reaction?

as in the genome is found that all nature comes from the same organism (LUCA) is it possible that what is inside us may be acquired from other elements of nature, and it is disturbing that the neurones connectors have an important similitude in chemical composition of psilocybin, is it possible that generations of psilocibin use have generated these connections as we know them? is it consciousness a brain chemical reaction??

  • Dec 21 2011: electro-chemical reactions.

    Consciousness is the perception that emerges from massively parallel iterative electro-chemical neural processing. That is - lots of different parts of the brain, processing lots of different information, doing it all very very quickly, all at once, and repeatedly feeding processed information back into other parts of the brain... all operating on the electro-chemical substrate of neural interaction. When your visual center is working in concert with your memory, audio, emotions, etc, etc... the real time, iterative concert of all these disparate pieces causes the sensation of consciousness.

    But that's really as helpful as telling you that the functions of computer programs emerges from massively parallel iterative electro-mechanical transistor operations.

    It's accurate, and captures some of the spirit of how complexity emerges... but at the same time, leaves out significant portions of the intricacies and details of how these complex emergent phenomena comes to be.

    As far as psylocibin goes... that can chemically affect portions of the brain - specific neurotransmitters that perform certain tasks - which in turn would alter the way consciousness is percieved or works for the period in which the drug is active - but would have nothing to do with been the cause of consciousness.

      Dec 21 2011: "Consciousness is the perception that emerges ..." What's "perception," then? Consciousness?

      "... causes the sensation of consciousness." And what's "sensation," then? Consciousness?

      It's not easy for the working mind to examine the working mind. We seem to run into conceptual and linguistic black holes.
      • Dec 22 2011: It's not easy for the working mind to examine the working mind. But that doesn't mean it's impossible.

        And flippant linguistic observations aside - the points made still hold; this thing that we feel that we call consciousness, is the feeling/perception/sensation that arises from the 'massively parallel, iterative, processing' of many smaller elements of the brain.

        Without the context of the rest of massively parallel iterative experience... electrical signals from the skin indicating pressure and temperature (among other things) mean little. In the context of visual, auditory feedback, of temporal delays, as well as the context of thousands of other memory cues - the small parts of the experience of consciousness ties into and makes sense with the overall experience.

          Dec 22 2011: Nothing flippant in my reply, George, and no criticism intended. I'm just pointing out the difficulty of explaining consciousness without resorting to near-equivalent terms, like feeling/perception/sensation, all of which are aspects of consciousness. One unavoidably gets into a tautological spiral because the mind can only grasp its own function by reference to its own function.

          I have no quibble with your mechanistic explanation of nerve nets in the brain. As a biologist myself I think you said it as well as can be said in a paragraph or two.
        • Jan 13 2012: Mr. K. From what you are saying, it would appear to be very likely that conscious robot brains could be developed(?)
        • Jan 13 2012: shawn,

          I don't know if that's what Mr K said, but I am pretty sure that sometime humans will develop conscious "robot brains." I don't see why not.

        Dec 22 2011: You men are ridiculous
      • Dec 22 2011: Sorry Paul. Flippant wasn't the best word choice. Clever wordplay better resembles the connotations I was trying to impart.
    • Jan 13 2012: george: do you think the bacteria are there without knowing what to do? do you think functions of computer programs emerges from massively parallel iterative electro-mechanical transistor operations, well i dont, i see the simple, im not talking here about psilocibin, im talking about passion and evolution, and about a passion that makes us evolve, cientifics can say you where starts complexity, im talking about where is it driving us
