 Yah, the argument regarding the degree, or lack of degree of interaction
that quantum effects have on a more macro level I suppose holds quite well.
My curiosity was somewhat two-pronged -- firstly, are current models
regarding the complexity and processing power required for a reasonable
simulation of the human brain adequate (ignoring the necessary overhead that
a software implementation would entail), and secondly, a more general
curiosity regarding the degree of determinism implied if all human reasoning
is computable.

summarizing penrose's argument:

assume that my reasoning capabilities can be simulated by formal system F.
for every statement S of F that I determine true, S is a theorem of F, and
vice versa. Since I believe F describes my reasoning, I believe F is
sound. Since F is sound, G(F) (goedel) is true, but not a theorem of F.
however, since F is sound, G(F) is also true. However, G(F) is not a
theorem of F, but I know it to be true, therefore F does not describe my
