I'd say a simulation at the level of macromolecules would be necessary: the type, number, approximate location of proteins. Above that there is cellular anatomy and synaptic connections. Below that there are small molecules such as neurotransmitters and ions, which can be modelled from generic knowledge of neurons. It would be a relatively straightforward matter to run the model and compare with real neurons. The Blue Brain Project people think they will be able to simulate a generic human brain by 2023, and then it would be several more steps before a particular brain could be simulated - but I suspect these guesses, like "when will we have human level AI" - will keep being pushed back. If it behaves just like me then I would be confident that the upload is me, and I wouldn't mind a destructive upload. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
