I think the best avenue toward actually answering your questions starts with OpenWorm [1]. I helped out in a Connectomics research lab in college. The technological and epistemic hurdles are pretty daunting, but so were those for Genomics last century, and now full-genome sequencing is cheap and our understanding of various genes is improving at an accelerating pace. If we can "just" accurately simulate a natural mammalian brain on a molecular level using supercomputers, I think people would finally agree that we've achieved a truly thinking machine.
