A Purely-Electronic Brain -- Possible?

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.

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?

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.

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.
