Exactly. This is why microtubules look so weird, and they have to
postulate downright odd ways for quantum coherency to spread. The
latest paper I saw contained gap junctions galore, and I'm fairly
certain they aren't *that* common in the brain.

Neither of them is a neuroscientist (Hameroff comes closest, I think
he was opriginally an anesthesiologist), and both are definitely not
speaking about the areas where they are respectable. We shouldn't
trust people for being respectable established scientists, we should
look at their theories and the facts they presents.
