Voted up - liked the approach. But as always there are a few thing that I would rather look at differently. I think 'brain states' is a bit misleading and prefer 'brain processes'. It doesn't seem like the brain is a very static thing, passing from state to state. I also prefer to separate the ideas of thought and of awareness for clarity about which is being examined in any statement. This is nit-picking I know and does not take anything way from your argument.
