Dr. Stuart Hameroff, anesthesiologist and Professor at University of Arizona, believes that he has discovered the soul. Dr. Hameroff is well-known for his groundbreaking revelations in the study of consciousness and quantum biology.
His work in anesthesiology has led him to believe that overall brain function is derived from quantum level microtubule vibrations in a process he calls orchestrated objective reduction (Orch-OR). In a near-death experience the microtubules lose their quantum state, but the information within them is not destroyed. In other words, the soul does not die but returns to the universe.
