UrsusArctos: That's too large to be an actual human brain and no brain can stay preserved in a metal case like that, so it's definitely synthetic. (Curious what the scene description says) The idea that it's actually Naoko's brain, scooped out of her dead body, is just a misconception.
dzzthink: I'm curious how they managed to upload her personality at all into a machine. Before there was the matrix, this concept of the brain in a vat seems to be brought up in Evangelion. The method of destroying the Angel is also similar to the ending of Matrix 3 and Agent Smith.
