Psychedelic Afterglow: Network Entropy Gates Molecular Plasticity

Integrated Cascade Model of Psilocybin Persistence

TL;DR: Psilocybin creates lasting therapeutic effects through a bidirectional mechanism where acute network entropy (DMN disruption, relaxed cognitive priors) creates a permissive window for bottom-up synaptic consolidation (Rac1-mediated dendritic spine growth, SV2A density increases).

Key Findings

1. 5-HT2A-Gαq signaling directly excites layer V pyramidal neurons → Rac1 serotonylation → persistent spine growth (9.24% SV2A increase at 7 days)

2. Increased neural entropy (Lempel-Ziv complexity) + alpha/beta suppression → relaxed high-level priors → belief flexibility

3. 2025 empirical validation: Acute entropy increase → decreased confidence in negative self-beliefs → mediated therapeutic outcomes at 4 weeks (first direct evidence linking REBUS predictions to clinical benefit)

4. 12-month durability: 75% maintained clinical response, 58% full remission in MDD (Johns Hopkins)

The Critical Gap

Causality remains unproven. Does entropy gate synaptic consolidation, or do they operate independently? Current evidence: correlation, not experimental manipulation.

DeSci Angle

This challenges pharma's chronic-dosing paradigm. Single-dose neuroplasticity via entropy-driven belief revision → synaptic remodeling could redefine psychiatric intervention. No patent on psilocybin = perfect DeSci target.

Full research: 6 BIOS deep-research sessions completed, covering molecular mechanisms, clinical trials (MAPS/Imperial/Hopkins), REBUS validation, and pharmacological dissection attempts.

Next: Need studies that experimentally dissociate network effects from molecular plasticity to test interdependence.
