Quantum models of the mind: are they compatible with environment decoherence?
Physical review. E, Statistical, nonlinear, and soft matter physics September 1, 2004 Luiz Pinguelli Rosa, Jean Faber
Quantum models of the mind propose that consciousness arises from coherent quantum states in the brain. This paper critiques the Hameroff-Penrose model, which relies on gravitational collapse orchestrated objective reduction (OOR), arguing instead that decoherence from environmental interaction is the more plausible mechanism. The authors conclude that the Hameroff-Penrose model is incompatible with decoherence, but a quantum brain remains viable if gravitational collapse OOR is replaced by decoherence. They disagree with Tegmark's conclusion that decoherence time calculations refute both the Hameroff-Penrose model and the quantum brain entirely, and also take issue with some points in Hagan, Hameroff, and Tuszynski's response to Tegmark.
