I agree that it would be absurd to say that the qualia are fading if this makes no subjective or objective difference. This is why I think it is impossible to reproduce the behaviour of a brain component without also reproducing any associated consciousness.

It would mean that you were thinking with something other than your brain, which is not impossible, but does go contrary to all scientific evidence.
