Would you stop that? Nobody is attacking the Church-Turing Thesis, and
if we were it wouldn't necessarily have any religious implications.

We are arguing over whether neurons can be mapped to the individual
causal-transition tokens of a Turing machine, i.e. neurons would be the
bottom level of the brain. It is possible that:

1) Neural assemblies are the "bits" of the brain.
2) Neurons require complex systems to simulate.
3) Single synapses are the basic causal tokens of the brain.
4) [1..3]s are the causal tokens of the brain, but don't map easily to
Turing bits. RAM doesn't map well to Turing tape.
