What if you used a lookup table for only a single neuron in a computer
simulation of a brain?  So actual calculations for the rest of the
brain's neurons are performed, but this single neuron just does
lookups into a table of pre-calculated outputs.  Would consciousness
still be produced in this case?

What if you then re-ran the simulation with 10 neurons doing lookups,
but calculations still being executed for the rest of the simulated
brain?  Still consciousness is produced?

What if 10% of the neurons are implemented using lookup tables?  50%?
90%?  How about all except 1 neuron is implemented via lookup tables,
but that 1 neuron's outputs are still calculated from inputs?

At what point does the simulation become a zombie?
