I know consciousness does not NECESSARILY collapse the wave function. I also know about Wigner's friend, Wigner's friend's cousin, and Wigner's friend's cousin's gay black granddaughter.

I ALSO know about Orch-Or and its meme status, but that's not really what I'm talking about today.

What I would like to know is how small quantum effects, both the understood and not-so-understood, scale up to the classical brain structure, if at all. All of these vague concepts resting at our "understanding" of the subatomic level MUST scale up to have an effect on our thinking, right?
