Microtubules: cellular structure and computing analogy

Dr. Stuart Hameroff is an anesthesiologist, consciousness researcher, and co-creator of the Orch-OR theory — a radical and controversial model proposing that consciousness arises from quantum processes inside the brain’s microtubules.

For over 30 years, Dr. Hameroff has worked alongside Sir Roger Penrose to explore how the fundamental fabric of spacetime could give rise to awareness itself — and what that means for AI, life after death, and the mystery of subjective experience.

Expect to learn why microtubules inside neurons might be the real seat of consciousness, how anesthetics switch off awareness by dampening quantum vibrations, what happens to consciousness when the brain flatlines, why current AI models may never be truly conscious, how quantum coherence can persist in the warm, wet brain, what a "quantum soul" might actually mean, why critics have called this theory absurd — and how new research may finally be proving them wrong, how ultrasound could treat depression by targeting the roots of awareness, and much more...
