Orchestrated Objective Reduction (Orch-OR) is a theory proposed by physicist Roger Penrose and anesthesiologist Stuart Hameroff that suggests consciousness arises from quantum processes in the brain. According to this theory, quantum events in microtubules—tiny structures within neurons—can lead to moments of conscious experience when they collapse into definite states. The "orchestrated" part refers to the idea that these quantum collapses are not random but are influenced by biological processes, making them meaningful. This theory attempts to bridge the gap between quantum physics and neuroscience, offering a unique perspective on how consciousness might emerge from the brain's complex workings.
