Ralph Merkle's cryonics page is a good place to start. His 1994 paper on The Molecular Repair of the Brain seems to be the most technical explanation of why it looks feasible.
Since whole brain emulation is expected to use many of the same techniques, that roadmap (long pdf) is worth looking at.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
