Psilocybin and the Default Mode Network: What fMRI Actually Reveals
Functional brain imaging has reshaped our understanding of how psychedelics affect consciousness. We explain the Default Mode Network, what psilocybin appears to do to it, and the limits of what current evidence can claim.

Psilocybin vs. LSD vs. Ayahuasca: How They Differ
Classic psychedelics share core mechanisms but differ in important ways. We compare psilocybin, LSD, and ayahuasca across pharmacology, experience, duration, and clinical research.
REBUS, Entropic Brain, and What Psychedelics Do to the Cortex
Two influential theoretical frameworks have shaped how scientists think about psychedelic action in the brain. We explain the entropic brain hypothesis and the REBUS model, what they predict, and how the evidence has held up.
Tolerance and Cross-Tolerance with Psilocybin: What to Know
Psilocybin produces tolerance faster than almost any other recreational substance. We explain the underlying biology, what cross-tolerance means in practice, and the implications for both clinical and recreational use.
Fungal biology, species profiles, ecology.
The Genera That Produce Psilocybin: A Field Overview
Psilocybin is not the property of a single mushroom. It appears across several distinct genera that are only distantly related. We survey the main psilocybin-producing groups — Psilocybe, Panaeolus, Gymnopilus, Pluteus, and others — and explain what convergent evolution tells us.
The Fungal Life Cycle: From Spore to Spore
A mushroom is one brief moment in a longer story. We trace the complete life cycle of a fungus — spore, germination, mycelial growth, mating, fruiting, and dispersal — and explain the strange genetics that make fungi unlike plants or animals.
Mushroom Anatomy: A Complete Structural Guide
Every part of a mushroom has a name and a function. We walk through the full structure — cap, gills, stem, ring, volva, spore print, and the hidden hyphal network beneath — and explain why each feature matters for identification and biology.
Cultural and historical context of psilocybin use.
From Tek to Lab: A Brief History of Mushroom Cultivation
Cultivating Psilocybe mushrooms in homes and laboratories transformed access to psilocybin in the late twentieth century. We trace the technical history from early Stamets and PF Tek to modern lab-scale production.
Gordon Wasson and the Rediscovery of the Sacred Mushroom
In 1955, an amateur ethnobotanist became the first outsider to document a Mazatec mushroom ceremony. The story of R. Gordon Wasson, María Sabina, and the publication that changed everything.
María Sabina and the Mazatec Tradition: History, Encounter, and Aftermath
The Mazatec curandera who introduced the Western world to ceremonial mushroom use carried a tradition that long predated her — and bore lasting consequences from that exposure. This is the history, told carefully.
Effects, set & setting, harm reduction context.
Mushroom Identification Safety: Why Foraging Requires Real Caution
Misidentified mushrooms cause hospitalizations and deaths every year. We explain the actual risks of foraging, why apps and field guides are not enough, and what responsible identification looks like.
Set and Setting: The Psychological Frame That Shapes Every Experience
First articulated in the 1950s, the principle of set and setting underlies essentially all serious research on psychedelics. We trace its history, explain what it means, and examine why even careful researchers consider it inseparable from outcome.
Policy, law, art, media, broader cultural footprint.
The Stoned Ape Hypothesis: A Sober Look
Terence McKenna's claim that psilocybin mushrooms drove human cognitive evolution remains popular. We examine what the hypothesis actually proposes, what evidence would support it, and why mainstream science remains skeptical.
Psilocybin Legal Status Worldwide: A 2026 Snapshot
Psilocybin remains a controlled substance across most of the world, but the regulatory landscape is shifting. We map the current legal status across major jurisdictions, the recent decriminalization and medical approval developments, and the trajectories worth watching.
Practical guides to reading, observing, photographing.
The Stages of a Psilocybin Experience: A Phenomenological Map
What actually happens during a moderate-to-high dose psilocybin experience, from onset to integration. A clear, non-sensational walkthrough of the typical stages.
What Integration Actually Means After a Psychedelic Experience
Integration is the process of making sense of and acting on insights from a psychedelic experience. We explain what the term actually refers to, why it matters for outcomes, and what useful integration looks like in practice.
How to Read a Clinical Trial Like a Researcher
A practical guide to evaluating clinical trial papers, from sample size and blinding to outcome measures and conflicts of interest. We use psilocybin research as the running example, but the framework applies broadly.
