To clarify for others, the brain's activity depends on the behavior of an enormous number of particles, each of which behaves according to quantum physics. The reason we don't usually talk about quantum effects on the brain is that nothing 'interesting' is going on. Everything averages out and behaves in a way that can be adequately described by classical physics. It's only when you get down to the scale of individual molecules and atoms that we are forced to get quantum physics involved. If some quantum effect occurs to make an enzyme bind with one nearby molecules instead of another nearby molecule, it just doesn't matter.GarberMoisha said:The brain does not need quantum mechanics. So far at least, there is no indication that quantum behavior, which is just nature preventing certain kind of knowledge, plays any part in brain's activity.
