One of the world's leading researchers in consciousness studies brings the audience at SAND Italy up to date with the latest research into the relationship between the brain's neuronal firing and consciousness. He explains Penrose's illustrations of nonlocality and superposition as separations in spacetime geometry, focusing in particular on microtubules. He also discusses pi resonance groups in anesthetics and psychedelics, which point to involvement of microtubules, and collapse of the wave function. This is the only scientific explanation of consciousness.
