    Orchestrated objective reduction

    Controversial hypothesis of a quantum origin of consciousness

    Orchestrated objective reduction is a controversial theory postulating that consciousness originates at the quantum level inside neurons. The mechanism is held to be a quantum process called objective reduction that is orchestrated by cellular structures called microtubules. It is proposed that the theory may answer the hard problem of consciousness and provide a mechanism for free will. The hypothesis was first put forward in the early 1990s by Nobel laureate for physics Roger Penrose, and anaesthesiologist Stuart Hameroff. The hypothesis combines approaches from molecular biology, neuroscience, pharmacology, philosophy, quantum information theory, and quantum gravity. Wikipedia

    Penrose outlined a predecessor to Orch OR in The Emperor's New Mind, coming to the problem from a mathematical viewpoint and in particular Gödel's theorem, but lacked a detailed proposal for how quantum processes could be implemented in the brain.Stuart Hameroff separately worked in cancer research and anesthesia, which gave him an interest in brain processes.

In 1994, philosopher David Chalmers explained that neuroscience could help understand how the brain controlled physical processes, but the real challenge was figuring out why humans and other living beings had subjective experiences.

    In the 1980s Penrose and Hameroff (separately) began to address these issues, each against the grain of mainstream views. 3. Microtubules as Biomolecular Computers Hameroff had been intrigued by seemingly intelligent, organized activities inside cells, accomplished by protein polymers called microtubules (Hameroff and Watt, 1982; Hameroff, 1987).

    2. The Penrose-Hameroff Approach. Perhaps the most ambitious attempt to create a quantum theory of consciousness is the one of Roger Penrose and Stuart Hameroff. Their proposal has three parts: The Gödel Part, The Gravity Part, and the Microtubule Part. The Gödel Part, which is due to Penrose, is an effort to use the

    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.

    Jun 30, 2024Dr. Stuart Hameroff then had the idea that the collapse of wave functions occurs in microtubules within neurons after reading Sir Roger Penrose's book, The Emperor's New Mind. The combination of their ideas led to this quantum physics-based model of consciousness, now referred to as the Penrose-Hameroff model.
