Summary
Psilocybin's profound effects may stem from a surprising **biology** of cross-kingdom **communication**. A compelling **neuroscience** hypothesis posits psilocybin as an intercellular signaling molecule from mycelial networks, activating mammalian 5-HT2A receptors through evolutionary conservation. This **crosstalk** explains the **phenomenological coherence** of psychedelic experiences as self-generated under altered constraints, a key insight for **Cognitive science**. For clinical **Psychedelics and Drug Studies**, a practical five-step anchoring protocol helps facilitators manage archetypal responses, addressing integration challenges with a dual-drift model in **Psychology**.
Abstract
Abstract This paper addresses two critical gaps as legal psilocybin mental health services expand: practical clinical protocols for integration challenges, and a mechanistic explanation for phenomenological coherence that avoids both mysticism and reductive dismissal.Clinical Contribution: I introduce a dual-drift model (Mystification Drift and Messiah Drift) with a five-step anchoring protocol for facilitators managing archetypal responses during integration. These tools are immediately applicable regardless of theoretical framework.Mechanistic Hypothesis: Psilocybin functions as intercellular signaling molecule within mycelial networks. Human experiences result from cross-kingdom receptor compatibility—fungal coordination molecules activating mammalian 5-HT2A receptors through evolutionarily conserved indolamine architecture. Experiences are entirely self-generated but operate under altered constraint regimes, explaining coherence without requiring external information transfer.Evidence Base: The signaling hypothesis emerges from structural identity to neurotransmitters, functional necessity of chemical coordination in observable mycelial behaviors, evolutionary conservation across kingdoms, and chemical diversity suggesting vocabulary not single toxin. I identify this as the null hypothesis; alternatives require more assumptions.Testable Predictions: Temporal precedence, spatial topology mapping, coordination impairment upon blocking, complexity correlation, and environmental responsiveness—all empirically distinguishable from pure defense mechanisms.Therapeutic Framework: Detailed neuroplasticity mechanisms (BDNF, dendritic growth, DMN normalization), integration protocols, screening criteria, and facilitator responsibilities grounded in established neuroscience.The framework aligns with predictive processing models while generating clear experimental pathways for mycological research. Clinical protocols serve immediate practitioner needs; mechanistic hypothesis advances empirical investigation beyond current assumptions.
