Compass: 21-08-05 "Near death experiences" "Quantum computing in thehuman brain"

Discussion in 'Computing' started by Kissing Lettuce, Aug 22, 2005.

  1. A truly fascinating documentary on the brain and so called
    "near death experiences" and a show that was good to the
    point of not letting me get up to make a cuppa.....

    Interesting thing learnt during this show is that they say the
    neurons in a human brain contain themselves little micro tubules
    of inner structure that seem to work on a quantum level making
    the brain a kind of quantum computer. They say this might
    explain how people have an experience of seeing themselves during
    surgery and recounting events in the operating theatre.

    Be bloody marvelous if it is proven as a fact but also open up a
    whole lot of other questions about the nature of existence and
    consciousness.

    Biggest load of terminally silly crap I have seen for one hell of a long time.
    That is just what one terminally silly fool claimed.
    More fool them. All those fools were doing was fantasizing, stupid.
    Pathetic, really.

    Its called a theary rod.
    Terms like "They say this might" and "if it is proven" should have
    given that away.
    You claim this theary to be "terminally silly", well thats your
    keyboard givin right to say.. personaly i think your a pea brained shit
    head.
    Thats my theary and there is nothing you can do about it.

  6. I have a theory that you have no idea what a "theary" is.......

    Its called mindlessly silly bullshit by anyone with a clue.
    That fool waffling on about 'little micro tubules of inner structure
    that seem to work on a quantum level making the brain a kind
    of quantum computer' never said anything like that.

    <reams of your puerile shit flushed where it belongs>

    I wouldn't hold your breath. New Agers through the term "quantum" over
    everything to misappropriate some of science's mystique.

    What is the name of the documentary? Which channel was it on?

    and of the 60 cases at Southampton, where 4 had OBE's, why didn't the other
    56 have the same ?
    Bullshit. Penroses theory has been discredited. There is no quantum in
    micro tubles. See -

    And then what ? Want life after death do you ?

    btw that program was very old.
    I'm sure things have moved on from then.

    If you wanna know more about consciousness, study why similar mammals like
    dogs, cats and horses etc can't read, write and do maths.
    Then work out what might be the smiggin of difference we have with them

    the program was biased.
    as usual it purported to present things equally, but it had an agenda.
    'could be', 'might be' etc soon got turned to 'fact'
    the root of all religious belief is the hypothesis of life-after-death.
    take it away and you have what ? :)

  12. We know but it did seem quite appealing at the time the show was
    on. BTW there's nothing "new age" about the idea of a quantum
    computer..

    In theory such a machine would predict user input before the input
    was actually done.......

    No, but applying the term to the brain, which already has a perfectly
    reasonable and testable model for computation based on the reinforcement of
    pathways through the neurons is pointless.
    I knew you were going to say that.

    Brain's function can be deducted to the function of quantum theory and
    quantum computer, but in reality it's much more complex and can't always
    study in terms of rational thinking. The Quantum idea is probably closer
    than any other rational approaches but seems to lack any clear evidence.
    That's why these are philosophical questions rather than physical science. I
    don't think we have a clue and merely building model theories to understand
    the phenomena which get superseded by another in time. Just like Newtonian
    model of universe got replaced by Einstein's model of universe which
    rejected the idea of gravity and replaced it with Space-time. These are
    questions to seek answers in philosophical realm, at least physical science
    develop into a stage where it has enough knowledge to try to describe
    phenomena like after life(if there is, who knows).

    And mindlessly silly.
    Just another crutch for pathetically inadequate 'minds'

    Bullshit, everything can.
    Nope, the obvious rational explanation for what
    they claim to have seen is that they were fantasys.
    Not a shred of any evidence what so ever in fact.
    No they arent.
    That quantum bullshit is pure bullshit with how the brain works.
    It didnt actually get replaced at all, just refined to cover what
    happens when the speed approaches the speed of light.
    That didnt happen either.

    And with the brain, there is no need for any completely
    fanciful quantum bullshit when what they claim to
    remember has an obvious explanation, pure fantasy.
    Its obvious its a crutch for pathetically inadequate 'minds'

    And those silly fantasys dont add a damned thing to that question anyway.

    and this :

    The Neurobiology Behind Out-of-Body Experiences

    September 27, 2002

    You are floating several feet above the ground...

    You look down...

    You see.............YOU!

    You are not watching a TV episode of The X-Files or The Outer Limits.
    Rather, you are experiencing an "out-of-body experience" or an OBE.

    OBEs are brief sensations that occur when a person feels as if his mind
    separates from his body. During OBEs, people sense that they are floating
    above their own bodies. No one knows what causes OBEs, but some people
    believe that OBEs are religious or spiritual events. Interestingly, many
    people who have come close to death report that they have had an OBE.

    Researchers from the University Hospitals of Geneva and Lausanne
    (Switzerland) have found that OBEs can be produced by direct electrical
    stimulation of a specific part of the brain. Dr. Olaf Blanke and his
    colleagues worked with a 43-year-old female patient who suffered from right
    temporal lobe epilepsy. In order to identify the location where the
    seizures occurred, the researchers implanted electrodes on the brain under
    the patient's dura. While the patient was awake, the researchers could pass
    electrical current through the electrodes to identify the function of the
    brain area under each electrode.

    Electrical stimulation of the angular gyrus on the right side of the
    patient's brain produced unusual sensations. Weak stimulation caused the
    patient to feel as if she was "sinking into the bed" or "falling from a
    height." Stronger electrical stimulation caused the patient to have an OBE.
    For example, the patient said, "I see myself lying in bed, from above, but
    I only see my legs and lower trunk." Stimulation of the angular gyrus at
    other times caused the woman to have feelings of "lightness" and of
    "floating" two meters above the bed.

    The angular gyrus is located near the vestibular (balance) area of the
    cerebral cortex. It is likely that electrical stimulation of the angular
    gyrus interrupts the ability of the brain to make sense of information
    related to balance and touch. This interruption may result in OBEs. Blood
    flow changes within the angular gyrus may alter brain activity during "near
    death experiences." This may result in OBEs reported by people who survive
    such events.
