Quantum logic: the next brain adaptation?

  1. Dec 5, 2003 #1
    Have our brains come to the point in evolution where we could soon utilize them as mathematical matrices, noncommutative networks, and quantum logicians? Such reasoning may bestow the statistical benefits for predicting and understanding otherwise paradoxical or convoluted outcomes.

    If so, what changes in brain structure and function will enable this saltation? Might telepathy relate to these changes through interactive nonlocal correlations?

    If not, what physical complications may prevent its realization, and what instead will represent the next cerebral adaptation?

    I can say that there´s no obsticles for telepathy on this level of histo-cyto structure ...

    ¨Q:Do you think on brains in our heads or brains (or Tissue )isolated from body?

    I have no clue what you are saying :P

    Jhirlo, you think there are no obstacles for telepathy? Why do you say that and by which mechanism would you imagine it to work?

    I would rather ask if our brain has stopped evolving, rather than asking whether we could develop these amazing feats. Ofcourse, it would depend whether you are talking about an in vivo or ex vivo system.

    Could brains eventually be cultured in vitro from stem cells?

    How can a brain tissue/electronic computer interface be implemented?

    But first, please answer the questions originally asked above by this topic...


    The type of logic performed on the scale of atoms and below relies on noncommutative mathematical operations, just like for two matrices A and B:

    A x B does not in general equal B x A.

    Our brains now use familiar commutative operations like multiplication:

    A x B = B x A.

    If we were able to think in terms of quantum logic, we could approach currently intractable statistical problems with relative simplicity (see David Deutsch's The Fabric of Reality, Chapter Nine, I think).

    Perhaps our brains already have evolved and do calculate quantum mechanically on the atomic/subatomic level. I invite anybody to speculate as to examples of how Q. M. might affect our thinking. We still have room for improvement.

    All we need is some kind of a receiver and DAC or ADC :), it’s proved that there are people sensitive to some kinds of e-m radiation (wave to vets with metal plates in the head ;)). You can imagine some Fe aggregation connected to regular neurons like antenna modulating suitable neural signals :) (my imagination). Why not, we can digitalize radiation from 420-680nm, create hi frequency impulses (and low power radiate), it’s not impossible that we can’t develop, or some have, mechanisms to do the same with e-m waves from other parts of spectra.

    I believe I read something about men in some northern Europe land that won in Au¦Ö case proving that he feels cellular phones microwaves, resulting with court order that his fellow employees can’t use c. phones in his vicinity.

    Quantum computing using neurons – I don’t think so. Isolated neuro tissue wouldn’t be faster than average cpu in raw mathematical operations (my opinion). But we all know that the biggest speed isn’t speed of light it’s a thought ;).

    They've already achieved sorts of mechanical telekenisis with monkeys.

    "The Duke team implanted an array of microelectrodes into the brains of two female rhesus macaque monkeys. They implanted 96 electrodes in one animal and 320 in the other.

    They then analysed the signals given off by the electrodes as the animals were taught to use a joystick to both position a cursor over a target on a video screen and to grasp the joystick."

    How soon before the blind see with a camera, like the deaf hear with a cochlear implant?

    You know, this point reminds us of the fact that only artificial selection could yield this quantum logic adaptation. After all, there is no stimulus in nature to comprehend wave/particle duality or particle entanglement.

    Anyway, I think we're well on our way to finding such a "camera" that you refer to. I've heard of some research into nanotechnology that may soon yield a prototype of just such a device (though it would yield color-vision or even perfectly clear vision).

    Is evolution a classically correspondent process, or might radiation, isotopes, and microelectronic action be major components of quantum adaptation?
  11. Dec 13, 2003 #10
    I don't understand the question? It almost sounds like your asking me to choose between the Gould and Dawkins views (which I've finally come to a better understanding of). Please re-state.

    Evolution is variation filtered by natural selection. Any of the things you mention, and more, could be sources of variation in the genome. Selection however happens at the whole organism level (even if it is "on behalf of the genes"). So it is to a high degree of accuracy a classical process.

    In other words, I believe there may be shown organismic adaptations to cosmic radiation, to the presence of different isotopes, or to effects (like between neurons) not unlike those of microcircuitry, all on the quantum level.

    Would you mind outlining the Gould and Dawkins views?

    selfAdjoint seems to have addressed that selection itself, despite a quantal environment, is a classically correspondent process. I shall mull this over.
