Quantum Models of Mind: Are They Compatible with Environment Decoherence?
arXiv Preprint Archive March 5, 2004 Jean Faber, Luiz Pinguelli Rosa
The Hameroff-Penrose model of consciousness, which relies on gravitational collapse (orchestrated objective reduction, Orch OR), is incompatible with decoherence theory. Decoherence, caused by interaction with the environment, offers a more viable mechanism for quantum processes in the brain. Quantum mechanics can still be applied to brain research without the Hameroff-Penrose model by replacing gravitational collapse with decoherence.
