Microtubule Spark
Are quantum processes happening in the brain? Stuart Hameroff argues mind ignites when microtubule vibrations briefly lock into quantum coherence and collapse, a cycle he calls Orchestrated Objective Reduction. PBS New Frontiers filmed anesthesia suppressing those flickers as awareness faded Watch -->. His critics have long claimed quantum states perish in warm neurons, yet new data, including anesthetic and microtubule studies, bolster his case Profile and Popular Mechanics (paywall).
