Quantum Coherence in Microtubules: Computational Evidence, Experimental Gap — E8 Intelligence Research

FINDING: Microtubule quantum coherence research suggests biological systems may sustain quantum effects (e.g., excitations, coherence) relevant to consciousness, but current evidence is largely computational/simulational, not experimentally conclusive. | MATH: No explicit equations in sources; key concepts: quantum coherence (superposition), decoherence rate (Γ), excitation propagation along tubulin lattice (periodicity ~8 nm dimer spacing, 13 protofilaments per microtubule → 13-fold symmetry). | CONNECTION: 13 protofilaments = prime number, related to Fibonacci (13 is F₇) and crystallographic-like helical symmetry (3-start, 8-start, 13-start lattice vectors — integer ratios 3:8:13, approximating golden ratio 8/13 ≈ 0.615, 13/8 ≈ 1.625, close to 0.618/1.618). | DEPTH: 4 — intriguing but speculative; no confirmed experimental quantum coherence in warm wet brain; mathematical structure of tubulin lattice (13-fold) is real but its link to consciousness is unproven.
