The science

What is neuroplasticity — and why academic researchers are studying it alongside psychedelic compounds

Neuroplasticity is the brain’s capacity to reorganize itself by forming new neural connections. This capacity continues throughout adult life. It is the foundational concept behind learning, behavioral change, and recovery from certain neurological conditions.

A body of peer-reviewed literature — published in journals including Neuron, JAMA Psychiatry, and Pharmacological Reviews — has examined whether and how certain psychedelic compounds interact with neuroplastic mechanisms. This page summarizes that published research neutrally, without clinical claims or use guidance.

The goal of this resource is to present the peer-reviewed evidence clearly, accurately, and without commercial framing, for residents who want to understand the science.

“The brain has the remarkable ability to reorganize itself by forming new neural connections throughout life.”
Important context. All research cited on this page was conducted in supervised laboratory or clinical settings. The findings describe what researchers observed under controlled conditions. Nothing on this page constitutes guidance for personal use, commercial purposes, or any specific practice.
Mechanisms under investigation

What researchers are examining

🧠
Synaptic plasticityStrengthening or weakening of neural connections based on activity — the mechanism underlying learning and memory consolidation
🌳
BDNF expressionBrain-Derived Neurotrophic Factor: supports neuron survival, growth, and connection formation. Examined in multiple psychedelic compound studies.
🌐
Dendritic spine densityPhysical contact points between neurons. Yale’s 2021 study in Neuron observed changes in this measure in a controlled research setting.
🔄
Default Mode Network activityA brain network associated with self-referential thought. Reduced activity has been measured in clinical psilocybin research.

Several Bay Area universities and research institutions are active participants in psychedelic science. This resource presents the published findings in plain language, for informational purposes only. No inference about personal use should be drawn.

Published theoretical framework

The REBUS model: how researchers describe psychedelic compounds and the brain’s prediction architecture

REBUS — Relaxed Beliefs Under Psychedelics — published by Carhart-Harris and Friston in Pharmacological Reviews (2019). A theoretical framework for understanding the neurological mechanism of psychedelic compounds.

The core concept

🗃
Predictive processing theory
Modern neuroscience describes the brain as a prediction machine generating top-down expectations updated against sensory input. These predictive structures can become rigid — linked in literature to certain mood disorders.
🔓
The REBUS hypothesis
Carhart-Harris and Friston proposed that psychedelic compounds temporarily reduce top-down predictive signal dominance, resulting in increased bottom-up sensory processing and reduced cognitive rigidity.
📊
Default Mode Network findings
Multiple controlled studies measured reduced Default Mode Network activity under psilocybin. The DMN is associated with self-referential thought. Reduced activity has been correlated with depression measure improvements in clinical settings.
🔍
Research status
REBUS is a theoretical framework, not a clinical protocol or treatment guideline. It is among the most cited frameworks for understanding the mechanism of action of psychedelic compounds. Active investigation continues.
Theoretical framework only. REBUS is a scientific hypothesis published in a peer-reviewed journal. It is not a clinical guideline, treatment protocol, or recommendation of any kind.

Peer-reviewed research summary

What the published literature reports

The following is a neutral summary of published, peer-reviewed findings. All statistics describe outcomes observed in supervised research or clinical trial settings. They are not claims about personal outcomes.

All findings apply exclusively to supervised laboratory and clinical research contexts. No inference about personal use should be drawn.
1
Structural neural changes observed with psilocybin — Shao et al., Yale University
Neuron, 2021. Researchers observed changes in dendritic spine density in the prefrontal cortex within 24 hours of psilocybin administration in a controlled laboratory setting. Findings were documented in a controlled preclinical research setting.
Preclinical research — controlled setting
2
FDA Breakthrough Therapy Designation for psilocybin research
Granted in 2018 and 2019 for separate indications. Breakthrough Therapy Designation is granted based on preliminary clinical evidence to expedite development of promising therapies. It is not an approval and does not indicate commercial availability.
Regulatory designation
3
Johns Hopkins psilocybin trial for major depressive disorder — Davis et al., 2020
JAMA Psychiatry, 2020. A double-blind randomized controlled trial conducted with trained clinical support in a supervised setting. Researchers reported response rate outcomes at a 4-week follow-up point. The controlled conditions of this trial are not replicated in personal use contexts.
Randomized controlled trial — supervised clinical setting

REBUS and the Anarchic Brain — Carhart-Harris & Friston, 2019
Pharmacological Reviews, 2019. A theoretical neuroscience paper proposing a mechanistic framework for understanding how psychedelic compounds interact with predictive brain processing. Theoretical model, not a clinical guideline.

California legal status — SB 58 vetoed October 2023
California SB 58, which would have decriminalized psilocybin for personal possession, was vetoed by Governor Newsom in October 2023. California has not enacted statewide psilocybin decriminalization. Psilocybin remains Schedule I under federal law and controlled under California law outside approved research settings.

Neuroplasticity is the brain’s capacity to reorganize itself by forming new neural connections throughout life. It underlies learning, memory, behavioral change, and recovery from certain neurological conditions. A body of peer-reviewed research has examined whether certain psychedelic compounds interact with neuroplastic mechanisms including dendritic spine density, BDNF expression, and Default Mode Network activity. This research is ongoing and conducted in supervised laboratory and clinical settings.
REBUS stands for Relaxed Beliefs Under Psychedelics. Published by Carhart-Harris and Friston in Pharmacological Reviews (2019). The model proposes that psychedelic compounds temporarily reduce top-down predictive brain signals, allowing more flexible information processing. This is a theoretical framework, not a clinical guideline or treatment protocol.
The Shao et al. 2021 Yale study (Neuron) observed structural neural changes in a controlled preclinical research setting following psilocybin administration. The Davis et al. 2020 Johns Hopkins study (JAMA Psychiatry) was a double-blind randomized controlled trial reporting outcomes at 4-week follow-up among participants receiving psilocybin-assisted therapy in a supervised clinical context with trained clinical support. Both studies were conducted in strictly controlled research settings. Specific outcome figures should be read within the full context of each published paper.
The FDA granted Breakthrough Therapy Designation to psilocybin-assisted therapy in 2018 and 2019. This designation is a process designed to expedite the development of drugs showing substantial preliminary improvement over existing therapies. It is not an approval for commercial use, does not indicate availability, and does not apply to personal administration outside of clinical trials.
