Question for all of you: Is our subconscious conscious? That is, are parts of us conscious? "I" am the top-level consciousness thinking about what I'm typing right now. But all sorts of lower-level processes are going on below "my" consciousness. Are any of them themselves conscious? Do we have any way of predicting or testing whether they are?

Tononi's information-theoretic "information integration" measure (based on mutual information between components) could tell you "how conscious" a well-specified circuit was; but I regard it as an interesting correlate of processing power, without any demonstrated or even argued logical relationship to consciousness. Tononi has published a lot of papers on it - and they became more widely-cited when he started saying they were about consciousness instead of saying they were about information integration - but he didn't AFAIK make any arguments that the thing he measures with information integration has something to do with consciousness.
