We would already need Clarketech to revive any dead brain. If we are entertaining theoretically possible future tech: Provided there are enough neurons and it would be possible to reconstruct their connections, we could scan them, create a custom built model for the rest of the brain (the part that is missing/unrecoverable), plug it in and simulate it. Consciousness debate aside, we might be able to recover some memories from it and talk to it. But my guess is that all the data is lost already.
