We also speak of surface correspondence. in addition to synaptic correspondence, to verify that some tiny little overlooked property of the synapses wasn't key to high-level surface properties, in which case you'd expect what was left to stop talking about consciousness, or undergo endless epileptic spasms, etc.

Hmm. I would expect a difference, but ... out of interest, how much talk about consciousness do you think is directly caused by it (ie non-chat-bot-simulable.)
