Psilocybin First Use Changed Brain Signals for 1 Month

MHD featured image for first-time psilocybin use, brain entropy, MRI changes, and psychological insight.

A 2026 mechanistic study involving 28 healthy adults found that a single 25 mg psilocybin session changed acute brain entropy, psychological insight, well-being, cognitive flexibility, and some MRI-derived white-matter signals for up to 1 month. Research Highlights Acute brain entropy rose clearly: 25 mg psilocybin increased Lempel-Ziv complexity (LZc; a measure of signal irregularity) at …

Psilocybin Reduced Fish Aggression Bursts in Rivulus Study

MHD featured image for psilocybin effects on aggression and activity in a mangrove rivulus fish model.

A 2026 study involving 32 adult mangrove rivulus fish pairs found that 3,000 µg/L waterborne psilocybin reduced movement and aggressive swimming bursts, but the result belongs in animal behavioral pharmacology, not in human aggression treatment claims.1 Research Highlights Fish movement decreased: psilocybin produced a treatment-by-time interaction for time spent moving (p = 0.006), with a …

Psychedelic Hallucinations May Reflect Wake-Time Memory Replay

Photoreal illustration of a brain shifting between perception and generative imagery under psychedelic influence.

A 2026 eLife computational study modeled classical psychedelics by increasing a network state variable from alpha = 0 to alpha = 1, shifting perception from bottom-up sensory inference toward top-down generative replay. The result is a useful but still unproven oneirogen model: hallucinations look less like random noise and more like wake-time replay of a …

Are Mystical Experiences Required for the Antidepressant Effects of Ketamine & Psychedelics?

The intersection of mental health treatment and pharmacology is witnessing a remarkable shift with the growing interest in ketamine and classic psychedelics like psilocybin for their rapid and sustained antidepressant effects. Unlike traditional antidepressants, these substances offer hope for those with treatment-resistant depression by potentially transforming treatment paradigms. However, it remains somewhat unclear as to …

Effects of DMT on Mental Health: Depression & Anxiety in Healthy Adults (2024 Study)

In the quest for innovative treatments for psychiatric disorders, the study of psychedelics has taken a significant leap forward. Among these, Dimethyltryptamine (DMT), known for its rapid onset and short duration of action, emerges as a compelling alternative to traditional therapies. Recent studies have begun to explore its potential, particularly in treating depression and anxiety, …
