A recent groundbreaking experiment in which anesthesia was administered to rats has convinced some scientists that tiny structures in the rodents’ brains are responsible for the experience of consciousness. To pull it off, microscopic hollow tube structures called “microtubules” perform some advanced physics; the experts believe microtubules perform incredible operations in the quantum realm. Citing the work of earlier researchers, the study infers that the same kinds of quantum operations are likely happening in the human brain.
