From Bladder to Dream: A Quantum-Classical Cascade Model of Neural Binding and Conscious Integration

The binding problem --- the question of how spatially distributed neuralactivity gives rise to unified conscious experience --- remains one of thecentral unsolved problems in neuroscience. Existing quantum approaches toconsciousness, notably Orchestrated Objective Reduction (Orch~OR), have beencriticized on the grounds that biological decoherence timescales (\!10^-13\, s) preclude sustained quantum coherence in the warm, wetneural environment. Here we argue that this timescale, far from being anobstacle, is precisely compatible with the vibrational dynamics of hydrogenbond networks, which operate in the terahertz regime (10^12--10^13\, Hz). We propose a hierarchical quantum-classicalcascade model in which quantum tunneling initiates local coherent islandswithin hydrogen bond networks at the molecular scale, which are then relayedacross dendritic arbors via conventional ionic mechanisms, re-initiatingcoherence at successive molecular nodes. This architecture naturally accountsfor the global neural coherence observed during dreaming, wherein peripheralphysiological signals are seamlessly integrated into narratively coherentexperiences across spatially distant brain regions in the absence of externalsensory input. We derive falsifiable predictions regarding terahertzspectroscopic signatures in active neural tissue and propose that disruptionof hydrogen bond network geometry should selectively impair dream coherenceand associative memory retrieval. Our model bridges quantum biology, neuroscience, and the phenomenology of consciousness without requiringmacroscopic quantum coherence at any stage.
