If they are making these decisions, however complex, from programming,
then they are finite-state. If they are altering their circuitry in response
to
feedback loop from the environment, then they might be infinite-state
(analog).

Human brains are 'plastic' and rewire their circuitry. This is
not disputed by anybody, except by you it seems.

The physical "brain" is not conscious in the sense that you
could stick it with a pin and it wouldn't feel pain (no nerve
endings). But we, organisms including our brains have
"experience", mental life or "self-referential consciousness." Only
radical behaviourists deny this, are you a Skinnerian? If so
I can trot out the standard refutation of this position .......

The brain generates the virtual sensor(gan) in so that part
of our biosphere is non-material ... like can only interact
with like ... thoughts, dreams &c. are hallucinations or illusions
and can take place in/ interact with an organ that is purely matter.
This is Spinoza & Leibnitz case against Descartes' pineal gland
theory. MVT overcomes such objections.

random-like is not the same as random.

You are avoiding the point ... besides, perhaps pure randomness
is just a concept and does not exist in nature? Rapid eye movements
*seem* random in the same way that phasic transients *seem* random.

Ah, first they must self organise, then they must be
self-disorganised... You seem confused.

In order to make an *independent* response to the environment some
degree of "self" (organisation/ choice/ reaction) seems necessary.
A robot that blindly follows a set of instructions and cannot make
independent
volitions has no "self" or central executive, but is just a slave machine.
Yes, the ability of the brain to self-organise (or internally organise, if
you dislike
the term "self") is basic .. and indeed, human embryos spend up to 24 hrs a
day
in REM before birth at certain stages, and well after birth the neuronal
circuits
form and reform. There is a massive volume of data on ontogeny ... if you
insist I
will bore this list with reams of references?

The loci of experience, and the mechanisms that give rise to it are
very pertinent to the parallel discussion about uploading &c. Cogito ergo
sum.

What I am saying is that brain-dead (mu-state) means NO awareness.
The brain is not only a circuit, but needs to be in infinite state. I tend
to
think insect neuronal clusters, and even hagfish & lampreys (E-2 brains)
are not conscious. If the word conscious is a problem, use sentience or
even qualify as "self-referential consciousness."

Do you claim that dreams are anything more than automated backup/sorting
of buffer data stored in short term memory?

Yes, I agree with Globus (Real Time Hypothesis) that REM occurs during the
day
but is harder to detect, and with Aristotle that we are nearer to our true
"self"
when dreaming and mentation is not interrupted by external 'noise.' I also
agree
partly with Freud, and think that dreams are a way of rehearsing behaviour
(such
as sex) without taking risk of actually engaging in the world. We build and
destroy
models of reality when dreaming ... I also think that consolidation and
reinforcement of
memory (and discard activity) happens during dream, both REM and non-REM.

Your view is too narrow, and ignores loads of evidence. But at least you
accept
dreams (a form of conscious event) occur!
