The first thing you would need to do is to PROVE that the brain
works in the same manner as a neural net.  That should keep you
busy for a while.

Hint:  There's a lot of things going on in neurons that no neural
net that I know of can mimic.  This fall, I'm going to take a
rather intense course in neural networks, but without the delusion
that I'm studying the brain in the process.
