- Orchestrated_objective_reduction abstract "Orchestrated objective reduction (Orch-OR) is a controversial 20-year-old theory of consciousness conceptualized by the theoretical physicist Sir Roger Penrose and anesthesiologist Stuart Hameroff, which claims that consciousness derives from deeper level, finer scale quantum activities inside the cells, most prevalent in the brain neurons. It combines approaches from the radically different angles of molecular biology, neuroscience, quantum physics, pharmacology, philosophy, quantum information theory, and aspects of quantum gravity.While mainstream theories assume consciousness to emerge from complex computations performed by communicating cerebral neurons through synapses, Orch-OR posits that consciousness is based on non-computable quantum processing performed by qubits formed collectively on the microtubules of the cells, a process significantly amplified in the neurons. The qubits are based on oscillating dipoles forming superimposed resonance rings in helical pathways throughout microtubule lattices. The oscillations are either electric, due to charge separation from London forces, or most favorably magnetic, due to electron spin—and possibly also due to nuclear spins (which can remain isolated for longer periods of time), and occur in gigahertz, megahertz and kilohertz frequency ranges. The orchestration refers to the hypothetical process by which connective proteins, such as microtubule-associated proteins (MAPs), influence or orchestrate the state reduction of the qubits by modifying the spacetime-separation of their superimposed states. The later is based on the Diósi-Penrose scheme for interpreting quantum mechanics, which postulates the existence of an objective threshold governing the collapse of quantum-states, related to the difference of the space-time curvature of these states in the fine scale structure of the universe.The basis of Orch-OR has been harshly criticized from its inception by mainstream mathematicians, philosophers, and scientists, forcing the authors to revise and elaborate many of the peripheral assumptions of the theory, but the core ideas have remained the same. The criticism was mostly drawn on Penrose's interpretation of Gödel's theorem to assume the non-computability of consciousness, on the abductive reasoning linking that non-computability to quantum processes, and on the unsuitability of the brain to host the seemingly delicate quantum phenomena required by the theory, since it was considered too "warm, wet and noisy" to avoid decoherence.".
