             You become so focused on your task that you use almost none of your
            personal long term memories.  In principal, large portions of your 
brain
            could be disconnected without impacting your performance or 
experience.


        I think that is very doubtful.  You seem to equate memory entirely with
        conscious narrative memory, but what we think consciously is only a 
small part
        of our thinking.  In fact it might be a quite small part that could be
        disconnected.  When I think of the solution to a problem it often just 
'pops
        into my head'.  It obviously depended on my memory, because, for 
example, I
        didn't just unconsciously invent calculus to solve it.


    Think of how many neurons are dedicated to other things completely 
unrelated to
    taking the test: appreciating music, catching a baseball, tasting food, 
swimming,
and so on.

    How do you know that catching a baseball is *completely* unrelated?  I very 
much
    doubt that there is a one-to-one mapping between functions and neurons.


What is the information content of your current experience compared to the information content of your entire brain? Do you think they are approximately 1:1, 1:10, 1:100?

I would guess it is somewhere less than 1:10, and thus the majority of the "me" in my brain is of no consequence to my current observer moment,

How long is an observer moment? How about 1/100th of an observer moment? Taking a test usually takes an hour. How are moments strung together to make "you"?

though there is little existing data regarding the information content of our conscious experience, if you look at the bandwidth of the optic nerve, or auditory nerves, they are very low compared to the total estimated storage capacity of the brain. What makes this calculation more complex is that memories are integral to experience; about half the traffic that goes into the visual cortex is from memory, and the other half from the eyes.



    Certianly, our experiences shape us in ways we aren't always aware, and 
unconscious
    thought plays a big part of solutions we come up with, but when you are for
    instance, meditating and thinking of almost nothing, but how much of what 
you
    consider uniquely defines you as an individual, really goes into that 
experience?
    (of meditating, concentrating on an SAT question)?

    What uniquely defines me as an individual (if I am unique) is my 
moment-to-moment
    position and viewpoint as well as my stream of consciousness over time 
intervals.  I
    may have the same thought as you momentarily, but I'm seeing a different 
room and
    typing on a different keyboard and my next thought is different than yours.


If two people are in the same virtual reality so they see the same room and type on the same keyboard, and they happen to have the same thought,

Then they are the same person in the virtual reality.

what principal do you use to say one thought is Brent's and another thought is that person's?

If this is a virtual reality and there's another instance of exactly the same virtual reality - then I'm Brent in both of them. Otherwise, I'm the one on the left.

Brent
