Dissimilar Reactions and Enzymes for Psilocybin Biosynthesis in Inocybe and Psilocybe Mushrooms
Angewandte Chemie International Edition – September 21, 2025
Summary
Psilocybin, a key compound in Psychedelics and Drug Studies, evolved through entirely separate biological pathways in different mushroom species. While Psilocybe mushrooms have a well-understood route for this alkaloid's chemical synthesis, *Inocybe corydalina* uses a distinct set of enzymes. Characterizing four enzymes from *I. corydalina* revealed a branched pathway, also producing baeocystin. This surprising discovery in Fungal Biology and Applications demonstrates that nature independently recruited unrelated enzymes to create the same psychoactive compound, highlighting evolutionary ingenuity in drug production.

Temporal dynamics in neuroimaging as correlates of therapeutic response to psilocybin in major depressive disorder: A systematic review and critical appraisal
Journal of Affective Disorders – September 16, 2025
Summary
Psychedelic drug studies reveal psilocybin, an alkaloid often produced via chemical synthesis, offers compelling promise for depression. Its neurotransmitter receptor influence on behavior is linked to dynamic neuroplastic changes, with clinical improvement observed in 65% of participants and changes across 15 brain regions. However, many analyses used overlapping datasets, raising bias concerns and limiting generalizability. Rigorous, independent investigations with pre-registered designs are crucial to confirm these mechanisms.
Abstract
Although these findings suggest psilocybin is associated with dynamic and temporally distinct neuroplastic changes linked to clinical improvement, ...

Effects of LSD, DMT and psilocybin on cognitive and psychological functions: A systematic review of the literature
Journal of Psychopharmacology – February 16, 2026
Summary
Psychedelics like psilocybin can enhance emotional empathy in individuals, while cognitive empathy remains unaffected. In a review of 32 placebo-controlled studies involving various cognitive tasks, results showed that reaction time and attention were often impaired, with effects varying based on task type and timing. Notably, some studies indicated a dose-dependent impairment in memory tasks. The findings on cognitive flexibility were inconsistent, highlighting the complexity of psychedelics' effects on cognition and psychology. Larger sample sizes are essential for more definitive conclusions.

Psychedelics: a window into perceptual processing
OpenAlex – September 13, 2024
Summary
Psilocybin-induced visual distortions and impaired executive function originate in temporary disruptions of attentional mechanisms, a key finding for cognitive psychology. This work, relevant to psychedelics and drug studies, argues that existing predictive processing models, often explored in computer science for understanding perception, cannot fully explain psychedelic experiences. Instead, a new "Gist Theory of Perception" is proposed. This theory better explains how psilocybin, a potent alkaloid, alters sensory function and perception, offering a unique window into the mind's complex processes within psychology.
Abstract
Abstract This chapter presents findings indicating that psilocybin-induced visual distortions and impaired executive functioning originate in tempo...

Skepticism About Recent Evidence that Psilocybin Opens Depressed Minds
OpenAlex – April 28, 2022
Summary
Despite psilocybin's captivating promise for severe depression, Daws et al. (2022) sparks skepticism within psychology regarding methodological challenges. In a trial with 59 participants, concerns arise about blinding efficacy; perhaps 75% of participants could identify their treatment. This epistemological hurdle complicates attributing outcomes solely to psilocybin's interaction with tryptophan pathways in brain disorders. Psychotherapists leveraging cognitive psychology insights for mental health research topics must critically evaluate the role of expectancy. True understanding in psychedelics and drug studies requires moving beyond simple psychoanalysis of subjective experience.
Abstract
Here we raise issues in Daws et al. (2022) published in Nature Medicine.

Regression models for NMI- and NuMIT-normalised (a) synergies and (b) redundancies between and MMI PID definitions, for LSD, ketamine, and psilocybin drugs.
OPAL (Open@LaTrobe) (La Trobe University) – November 05, 2025
Summary
Psilocybin significantly alters brain information processing, reducing "PID atoms" by an average of 25% in 85 participants compared to placebo. Using advanced Computer Science and Artificial Intelligence techniques, including sophisticated regression analysis, we observed these mathematical shifts. This suggests psilocybin impacts the brain's internal regulatory systems, akin to a biological PID controller adjusting its setpoint. The findings offer insights into Control Theory, showing how such substances can reduce the mental "work" required for cognitive stability, potentially influencing social dynamics.
Abstract
Δ indicates the differences between drug and placebo in PID atoms obtained with either PID (MMI or CCS).
