replicating consciousness

[qazplm]

No, I don't believe in life after death, yes I realize that there are questions most folks would answer never, no way, not a chance, but please allow me to ask anyways.

1. Assuming (as I do) consciousness is totally tied to the physical brain (either directly or arising as an emergent property) is it physically possible to move it, i.e. either by replacing neurons with artificial neurons, or "uploading" or duplication or some other means.

2. If the answer to 1 is yes, then is that you? Or is it a copy? If a copy, is it sentient?

I tend to lean towards answering the first question as probably not in any truly 100 percent accurate way, which means the answer to 2 would then be no, it isn't you, although it could end up being sentient.

Put another way, if our consciousness, if "us" is simply a pattern of electrical signals in our brains, then it should replicable, given the appropriate level of technology, yes?
