Thanks for the link Chris.
It has also been discovered, some years ago, that glial cells are
involved in chronic pain. Since then, I follow them closely. They do
communicate chemically in some wavy way, and they do communicate to,
and influence, neurons.
I still tend to think that neurons play the key role in the
information treatment, and probably in the basic loops needed for
consciousness, but I would not been astonished, that glial cells would
be important for surviving some long period of time.
(Needless to say, for the UDA reversal, this is only a matter of
making the substitution level lower, and this does not change the
consequences.)

Liz - The pace of what we are discovering about the brain makes
everything we know about it a moving goal post; case in point the
key role it now appears astrocytes or glial cells play in the
formation of memories. Astrocytes account for around 90% of all
brain cells. This indicates to my view of things that until we
really do understand the actual mechanisms (and the second follow on
ring of emergent meta-mechanisms that characterize and emerge within
vastly parallel networks as well), it is too early to put hard upper
boundaries on capacity. If we are just now discovering previously
overlooked critical actors for the formation of memories; do we even
really know that much about the physical mechanisms for memory in
the brain?
This is, as you may have guessed, a subject in which I am fairly
interested; I believe a rigorous micro and dynamic network scale
understanding of brain functioning is required in order to form a
theory of consciousness, self-aware intelligence etc. I also feel we
are getting tantalizingly close to a kind of gestalt moment when all
the pieces will emerge naturally as one whole dynamic elegant theory
that will win someone a Nobel prize and a grand understanding of the
brain/mind and of ourselves emerges.
Cheers,

Subject: Re: Eidetic memory and the comp hypothesis
This is a very interesting point. What is the estimated capacity of
the human brain? I seem to recalls some 10^17 bits being mentioned
somewhere, or at least that figure has stuck in my mind (but not
having an eidetic memory, or much of a normal one, I can't say where
from).

Eidetics and gurus can apparently time travel in this block-space.

The phenomenon of eidetic (photographic) memory is well established
as a reality. For an example of what it means, read the top answer
to thisquora.com question. People with this gift/disability remember
every moment of their lives in perfect detail. To me this raises
real questions about the comp hypothesis and the 'yes doctor'.
Consider the 'RAM' required for this type of recall. Memories are 3d
and 'retina' resolution. If we consider that an hour of Blu-ray
footage consumes about 30Gb, then some rough calculations show that
Blu-ray quality footage of an entire life of 60 years would consume
around 17,000 terabytes of storage. But these memories include
tactile, olfactory and cognitive channels as well as visual and
auditory information, and of course the resolution of the visual
system is far better than Blu-ray. I'd take a rough guess and say
that full recording of a person's mental experience in all external
and internal channels would have to require hundreds or even
thousands of times the bandwidth of Blu-ray. But even at what I'd
think would be an extremely conservative estimate of a hundred
times, we're up near two million terabytes (two exabytes). What's
more, there appears to be no strain, no sign of running out of space
at all, as if capacity was simply not an issue. This type of example
makes me really question whether digital prosthetics are a real
possibility at all - it looks to me strongly suggestive of a totally
different way of recording information, or even of the possibility
that recording and storage are the wrong metaphor entirely.
'Christian' in the above quora response says that he has little
means of distinguishing a memory from a live experience, making for
a very confusing mental life. This type of memory looks more like a
kind of time travel than a recording. Perhaps this is still
compatible with Bruno's version of comp - the universal subject
inhabiting the pure space of Number - but it's more problematic for
step one of the whole argument that leads to this vision, namely
saying 'yes' to a digital brain.
