referenceExisting methods related to the transformations between quantum coherence and correlations, as described in references [68, 69, 70], can guide research into how neural electromagnetic fields exhibit quantum coherence.
claimMathematical models simulating how correlated neural firing creates coherent electromagnetic fields could help researchers understand how these fields might exhibit quantum coherence properties.
claimThe density matrix formalism provides a framework for quantifying exciton delocalization in microtubules using measures of quantum coherence, a methodology that parallels the approach used to quantify proton delocalization in water ice systems.

claimQuantum coherence is highly sensitive to environmental interference, a process known as decoherence, which poses a significant challenge to the plausibility of quantum states surviving in the brain's warm and wet environment.
claimStudies on photosynthesis and bird navigation have demonstrated that quantum coherence can play a role in certain biological processes, highlighting the potential for quantum phenomena to influence complex systems under specific conditions.
claimThe Orchestrated Objective Reduction (Orch OR) hypothesis faces scientific skepticism and challenges regarding the maintenance of quantum coherence in the brain's warm, wet environment, a process known as decoherence.

claimMax Tegmark argued in 2000 that the brain is too 'warm, wet and noisy' to maintain quantum coherence for meaningful amounts of time.
claimMacrolevel states within the brain, at the molecular level or higher, could theoretically be superposed if they achieve quantum coherence, which is a state of being superposed and internally entangled without being destroyed by environmental interference.
claimFriedrich Beck and John Eccles (1992) and Stuart Hameroff and Roger Penrose (2016) have proposed concrete mechanisms for how quantum coherence might occur in the brain despite environmental noise.

claimIn the Penrose-Hameroff framework, tubulin states are assumed to depend on quantum events, which allows for quantum coherence among different tubulins.
Theories and Methods of Consciousness biomedres.us Jan 29, 2024 1 fact
claimOrchestrated objective reduction theory (ORCH-OR theory) fails to resolve the binding and decombining problems of consciousness because the quantum coherence required for the process fails to hold due to quantum decoherence.
