    Hi:

    Will it ever be possible to make a purely-electronic brain that is
    exactly like a human brain except that its uses purely-electric
    signals instead of electrochemical ionic signals?

    If so would this brain be able to link to actual human brain and
    transmit/receive/process/record/playback electroneural signals?


    Thanks,

    Radium

    1. I don't think that anyone has even the vaguest clue.

    2. It's not even known whether the brain's only signaling
    method is via electrochemical ionic means.
    Could a square circle fly? You're asking about the properties
    of something that, as of yet, is purely imaginary.

    Actually it is quite well known that the brain's only signaling method
    is most definitely not electrochemical ionic. The molecular and
    cellular biology of events at the synapse are quite critical as is the
    whole activity of the cell in gene expression, protein synthesis and
    degradation, up and down regulation of all the machinery involved and
    on and on and on. A computer replication of electrical signals is
    but a very remote cartoon model of real nerve activity.

    Someone said "If you can imagine it, you can create it" (Don't remember who)

    We (current technology) do not have the imagination yet.

    And we will not, is our life time.

    True. Many proteins are involved.
    Much of the transmission, reception, processing, recording, playback
    of neural signals take place in the form of different types proteins
    and difference concentration and whose concentrations change in rate
    and extent. It is common for the neural "signals" to consist of such
    protein chemical reactions. This is mostly non-electric.
    But couldn't the electrical equivalents of those neurobiological
    events be designed?

    Yes, but radically-non-standard
    programming methods are nec-
    essary.

    Radically-non-standard 'electron-
    ics' are necessary if you want to
    do it fast.

    I'd explain, but it's no-longer 'ap-
    propriate' for me to do so here.

  7. Congratulations for having just written something quite EPT. :)

    Your daydreams are off-topic in some groups posted, please
    limit them to the appropriate groups. Thanks.

    To those who aren't yet aware of Radium's posting style, it
    is a bit more like a kid with a simple idea that is just
    expanded on in daydream fashion without any attempt to focus
    on the minor details which are often show-stoppers. Such a
    basic consideration of requirments would be the norm for
    most people but Radium is not developing the ideas to a
    reasonable extent before throwing them out there for the
    public to debunkify... which wastes everyone's time in the
    end.

    Schrodinger's equation (or whatever the appropriate physics might be)
    can be set up with suitable boundary conditions to compute anything
    and everything that happens in the universe. The status of such a
    "simulation" is more properly a subject for late night bull sessions
    in a college dorm. Creating an "a purely electronic brain", as in the
    subject line, is at this time just as silly a notion.

    The AI people predicted computer speech recognition decades ago. The
    predictions about artificial brains are not nearly as accurate.

    I don't know anything anymore.

    Not possible man?

    In principle - maybe.
    Reality is different thing: more we know, more obstacles we encounter.
    Say, when an electron jumps from a neurotransmitter to a receptor or
    vice versa, it's a quantum effect. And it's influenced by brain's own EM
    field. Once you start thinking EM field, you get to the points where
    zeno effect bites you, or say ionic structures form quantum neural
    networks; so to do that properly, you'd need a quantum computer size of
    a brain, in order to calculate FFT in planck time IOW in no time:)
    Don't take this too seriously nor too precise; but the answer is simple
    - only hardware that can emulate a brain is a brain.

    BTW Radius I see you got a number of interesting and precise answers on
    various groups. Good thing with your crossposting is that you got rare
    interdisciplinary view on the topic.
    Would you care to make a compilation of answers and put it on a web page?

    Regards...

    Unfortunately, this particular view of how biological machinery works
    won't get too far on bionet.neuroscience which is supposed to be
    restricted to actual science.
     
  13. The position of opinion expressed by Josip Almasi is EPT-aligned.

    Hence it is also science-aligned, and something that I have no qualms
    accepting as a predigested and pure enough reflection of by the process of
    Science (as most broadly and completely defined) securely established
    principles, theories, insights, correlations (and etcetera suchlike
    'informational matter').

    Accordingly I also regard what J. Almasi wrote as a pleasant whiff (or
    sample) from an unofficial "S_EPT_IC think tank".

    IOW:
    I agree, and feel good to do so. %-}

    It's cheaper to just use a real brain.

    John,

    You wrote this message tomorrow. You might think about resetting your clock.

    There are a number of books out there saying this will be possible in our
    lifetime. Typically written by AI people but I think the whole shebang got a
    big kickalong with the author William Gibson many years ago. It became a bit
    of a fashion to dream about uploading and the like. The idea remains current
    and sufficiently popular to make me think about taking the idea of "memes"
    seriously. It's fun to play with though. If you were uploaded while still
    alive which you would be you? The uploaded one would experience life
    differently from you and hence would soon no longer be you so which you
    would be you?

    Nonetheless Jerry is right. I replaced my power supply recently, cmos dead,
    didn't reset date right. For a short time at least ahead by a day. Will
    never happen again ... .

    Thanks Jerry.
