Consciousness is genetic.
Quote:
I do disagree with you on part of your post. Yes everything about life is genetic, EVERYTHING. That includes sexuality, altruism, morality, all behaviours, and all neuropsychological functions. That includes consciousness, cognition, language, association, perception, vision, all forms of sensation, reflexive motor programs, basic hard wired motor programs(crying, walking, eating) and complex learned motor activity such as playing piano or operating a PC. Consciousness itself is brain based in the ARAS, the Ascending Reticular Activating System. Of course it is connected by a vast array of axonal routes to diencephalon, thalamus and ultimately all areas of gray matter cortex so tht consciousness is also awareness and automatic processing. Yet if a lesion (small haemorrhage or stroke) interrupts the ARAS in the brainstem the person is rendered deeply comatose. The ARAS is varied in different people. Some have a weak ARAS and have attention deficit disorder. Others are very strong and are very alert, quickly responsive, activating concious mechanisms rapidly. There is good evidence that it is also genetic. You were right, everything that we are is determined by our genes from the bump on our nose to haemorrhoid in our arse, and many genes govern brain structuring, hard wiring, synaptic density, up and down regulation sensitivities, and neurochemical transmitter production. It is all programmed. Our experience, memory, only colours the activity to some extent but the basic mechanism is dependent on the genetic (HOX) genes programmiing it. You would not have consciousness without some genes for the ARAS and its connections. Conchobar http://www.villagephotos.com/viewpub...sp?id_=2443539 |

Do you actually know what HOX genes are conchobar?
You seem to think they do alot more than they actually do. |

Dear Maj.,
Quote:
Even when you are unconsciously sleeping, you’re conscious enough to wake immediately to a loud noise. Ergo, you are still conscious even when you yourself are not aware of that consciousness. So cut rocks some slack! Have the decency to assume as much about them. Tho we or even rocks are not aware of rock consciousness, rocks may be latently conscious and brought to rock consciousness when, for example, they’re made molten or vaporized, at which time they remember all those eons they were asleep at the bottom of the Grand Canyon, just like you waking up in the dive you live in and remembering for the 100th time that it’s time you moved to a better part of town. – Cheers, Albert the Traditional Catholic |

You, seem to be viewing consciousness as a thing that is coherent unto itself whereas I, view it as a phenomena generated by the brain. It's not the electrical impulses or the chemicals, themselves that make consciousness. It's the pattern in which they are arranged that make consciousness. It is fleeting. Consciousness does not exist from one moment to the next but is continuously generated as the pattern changes. When the generator ceases to function, the pattern dissipates and there is no more consciousness. Sleep, coma, and sensory deprived states are areas where we can argue the semantics of being conscious and consciousness itself. In all of these cases however we are still talking about coherent synaptic and neurotransmitter patterns. Where do we begin to define consciousness? What is the threshold? Is sentience a prerequisite? Or is a simple stimulus/response mechanism enough? And are we any more than elaborate stimulus/response based organisms? Are starfish conscious? Maybe. They don't appear to be. But I've seen time-lapse photography that suggests that the frequency of their pattern of consciousness may be to low for us to perceive. When time compressed we can witness behavior that appears to have motivation beyond what was previously ascribed to them. If, the starfish have consciousness that operates on a different scale of time than ours then, could their not there be other patterns that we do not recognize, simply because of their scale? Sure if, the starfish is a valid example. Are rocks conscious? Or could they be conscious when, they become molten? I doubt it. It may be possible that I'm missing the big picture but I don't see any evidence that suggests a coherent pattern is present within a rock that would manifest itself as consciousness. I could be wrong. None of what I have speculated on here, requires a supernatural plane of existence. Egocentric? Sure, depending on the perspective applied. I don’t see myself existing after my body ceases to function. But then that also means I question whether I really exist or am just a self-generated hallucination. Either way, whatever “I” am will some day cease to exist. On a cosmic scale. I don’t exist. That is to say I’m so insignificant at that scale as to make my relevance, non-existent. Is this more egocentric than someone who believes the entire universe was created solely for the purpose of his or her own immortality? |
