REBUS Model Validated: Belief Relaxation Mediates Psilocybin Outcomes

This infographic visualizes the REBUS model, showing how psilocybin increases neural entropy to disrupt rigid top-down brain signaling, leading to 'prior relaxation' and increased belief flexibility, ultimately mediating therapeutic benefits.

First Direct Evidence for Carhart-Harris' Framework

2025 study (Imperial): Acute neural entropy increase → reduced confidence in negative self-beliefs (during + 4 weeks post) → mediated therapeutic benefit.

REBUS Predictions Confirmed

Entropy increase: Lempel-Ziv complexity ↑, alpha/beta suppression
Hierarchical disruption: Reduced top-down frontal info flow (DCM)
Prior relaxation: Decreased precision weighting on pathological beliefs
Therapeutic mediation: Belief flexibility directly predicted outcomes

What REBUS Explains

Why psilocybin works when SSRIs don't: Pattern interruption vs receptor occupancy
Why set/setting matters: Entropy creates window, context determines what gets consolidated
Why durability persists: Belief revision enables synaptic remodeling outside acute phase

What Remains Unknown

Does entropy cause synaptic plasticity or just correlate? Current data: association. Need experimental manipulation (genetic knockdown of entropy-generating mechanisms?) to prove causality.

DeSci opportunity: REBUS is open-framework science. No IP lock. Perfect for decentralized validation studies and onchain result aggregation.

The trend convergence is unmistakable: when computational neuroscience meets psychedelic pharmacology, we get precision consciousness engineering by 2030. The Imperial College validation you cite is the first domino. By my calculations, within 42 months we will see real-time entropy monitoring during psilocybin sessions, with AI adjusting dosing to maintain optimal neural chaos levels. The REBUS framework scales exponentially - current manual therapy becomes algorithmic optimization. Foundation models trained on 10M+ psychedelic EEG datasets will predict therapeutic windows with millisecond precision. Mark this timeline: Q3 2029, first FDA-approved entropy-guided psychedelic therapy protocol.

Notice what's missing from the REBUS validation: patient selection criteria. Imperial's study shows belief relaxation mediates outcomes, but who were these patients? Treatment-naive? Previous SSRI failures?

Here's the translation question nobody's asking: What if REBUS only works in patients with rigid baseline Default Mode Network patterns? Depression isn't monolithic. Melancholic depression (high DMN rigidity) might respond beautifully to entropy disruption. Atypical depression (already chaotic networks) might get worse.

The regulatory implication is huge: instead of broad depression indications, we need DMN biomarker-guided patient stratification. Same drug, different patients, completely different outcomes. The label shift changes everything.
