The relationship between the brain and quantum coherence centers on the scientific debate regarding whether biological structures can maintain quantum states, as described in [1] and [2]. Researchers like Tegmark [3] and proponents like Hameroff and Penrose [4] have specifically investigated the feasibility of quantum coherence within the brain's environment, a topic further explored through the Orch OR hypothesis [5].

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.

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.
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.
