Is Consciousness a Quantum Orchestra? Microtubules, Objective Reduction, & Orch OR | Stuart Hameroff

Stuart Hameroff MD is Professor of Anesthesiology and Psychology, and Director of the Center for Consciousness Studies at the University of Arizona in Tucson. Hameroff became interested in intelligent behavior of microtubules, protein lattices which organize activities within living cells. Hameroff and colleagues developed theories of microtubules as self-organizing molecular computers. In the 1990s Hameroff teamed with Sir Roger Penrose on the controversial Penrose-Hameroff "Orch OR" model of consciousness based on quantum computing in brain neuronal microtubules, a notion bolstered by recent evidence. Hameroff also organizes the biennial interdisciplinary conferences, The Science of Consciousness Conference. The Science of Consciousness (‘TSC’) conference is the world’s longest running inter-disciplinary gathering on the study of consciousness, the nature of existence, and our place in the universe. In 2025 TSC will be in Barcelona, Spain, July 6-11 (Workshops, Plenaries, Concurrents, Exhibits, Demos, Social, Poetry Slam, Dancing - AC Marriott Forum Hotel), preceding and in conjunction with The Festival of Consciousness, July 11-13 (Music, Art, Experiential, Inspiration, Spirituality, Education, Business, Evolution). Speakers include: Sir Roger Penrose, Donald Hoffman, Robert Lawrence Kuhn, Rupert Sheldrake, Deepak Chopra, Federico Faggin, Anirban Bandyopadhyay, and many others.
