Ultimately everything in the universe is built out of tiny quantum things and ultimately everything obeys quantum mechanical laws. The “connection” between quantum physics and consciousness is pretty famous these days, what with the Secret, Chopra, and stuff like that. But are more interesting quantum effects, like entanglement, quantum teleportation, and quantum computation used by the brain? Weirder things have happened (maybe not a lot weirder). The brain might use entanglement to correlate things on different sides of the brain, or rapidly organize information.
