Those who find connecting quantum mechanics and the brain repulsive should check out Quantum Cognition https://en.m.wikipedia.org/wiki/Quantum Cognition.

For some reason the mathematics of QM is extremely good at explaining counter intuitive phenomena that classical probability theory cannot (necker cube is a good example, where the mental state can be said to be in a superposition of the two cube orientations).

Mind you, this doesn't say anything about the actual mechanism. It could or couldn't be quantum but we'll never know if we just shrug the entire thing off as crackpottery.
