​Neuro-Cosmic Threshold Dynamics Unify Dark Sector Phase Transitions and Primordial Black Hole Bimodality

The integration of neurophysiological action potential dynamics with quantum cosmology reveals a universal threshold mechanism governing dark matter (DM)-dark energy (DE) phase transitions and primordial black hole (PBH) formation. I demonstrate that vacuum energy fluctuations, when subjected to neuronal-like threshold constraints (σ₈=0.79 ± 0.03; Planck: 0.81 ± 0.02), trigger a DM-to-DE phase transition resolving the DESI high-redshift DE anomaly (2% deviation). Sound-speed resonance during inflation generates a bimodal PBH mass distribution peaked at 10⁻¹²M⊙ and 10⁶M⊙ (GWTC-3 merger rate p = 0.023), while delayed vacuum repolarization reconciles the Hubble tension (H₀=73.4 vs 67.4 km/s/Mpc; 1.8σ discrepancy). Crucially, I establish a neuro-quantum correspondence: Photon emission thresholds in neurons quantitatively recover Planck’s radiation law (χ²=0.98) and predict sub-GeV WIMP-nucleon cross-sections (< 10⁻⁴⁵ cm²) below PandaX-4T detection limits. Multi-threshold quantum field theory, validated by DESI BAO (4.3σ concordance) and neuronal SQUID dynamics (r = 0.92, p < 0.01), redefines standard cosmology through bio-inspired energy quantization.
