> FWIW, this book gave me the idea that consciousness could be some sort of feedback loop involving the whole Universe (including you and me and everybody else) possibly via quantum entanglement

Then this book sounds like it's not worth reading. There is absolutely no need to invoke pseudo-quantum mumbo-jumbo to investigate consciousness. We don't understand the chemical operation of neurons well enough to say whether quantum effects are necessary for neural functioning (although they probably aren't). Most "quantum-looking" (i.e. obviously non-classical) processes happen at much smaller space and energy scales than the chemical processes we know are involved in cognition.

Quantum entanglement almost certainly isn't involved because it can't be used to transmit information and it requires high degrees of precision to make use of in the first place.

The brain's thermal noise floor is vastly larger than the scale of most "interesting" quantum effects.

Don't pan G.E.B. due to my wild-eyed speculation. I'm the one saying "quantum!" and waving my hands here, not Hofstadter. ;-)
