Psilocybin Prolongs the Neurovascular Coupling Response in Mouse Visual Cortex
OpenAlex – July 31, 2025
Summary
Psilocybin, a potent hallucinogen and alkaloid, profoundly alters brain function. Neuroscience reveals this psychedelic drug, which can be chemically synthesized, prolongs blood flow increases in the visual cortex without changing neural activity in awake mice.

A novel psychedelic, 1P-AL-LAD, acts as a prodrug, converting to AL-LAD as its primary metabolite through in vitro human liver microsome chemistry. This metabolism is crucial for its in vivo hallucinogen effects. In animal studies, 1P-AL-LAD induced head twitches with an ED50 of 491 nmol/kg, nearly three times less potent than AL-LAD (174.9 nmol/kg). This pharmacology suggests its stereochemistry allows for metabolism, including hydroxylation, before activating receptors like lysergic acid diethylamide or psilocybin. Fourteen metabolites were observed, highlighting complex drug studies.

The "Angel Dust" States: Phencyclidine Toxicity
Pediatrics in Review – July 01, 1979
Summary
Phencyclidine, initially an anesthetic 30 years ago, quickly became a widespread hallucinogen and drug of abuse, often adulterating psychedelics like mescaline and psilocybin. Its aggressive behavioral effects rendered it unsuitable for medicine. Now a preferred substance, it's consumed in polydrug patterns. Understanding such drugs, including Lysergic acid diethylamide and Methaqualone, is vital for psychiatry and drug studies, shedding light on Neurotransmitter Receptor Influence on Behavior, like Nicotinic Acetylcholine Receptors.

Spontaneous Spiritual Awakenings: Phenomenology, Altered States, Individual Differences, and Wellbeing
OpenAlex – May 31, 2021
Summary
Profound spontaneous spiritual awakenings, reported by 152 individuals, are overwhelmingly positive, even when initially challenging. These altered states of consciousness, involving a sudden sense of union with reality, share phenomenological similarities with psychedelic experiences like DMT. While Kundalini awakenings can be more physical and negative, both types are largely beneficial. Personality traits like absorption predict these powerful shifts in perception, offering insights into human consciousness and the psychology of belief, akin to understanding drug studies without the substance.
Abstract
Spontaneous Spiritual Awakenings (SSAs) are subjective experiences characterised by a sud- den sense of direct contact, union or merging with a per...

Aesthetic Chills Mitigate Maladaptive Cognition In Depression
Research Square (Research Square) – November 14, 2023
Summary
Experiencing aesthetic chills, those physical shivers, can significantly alter maladaptive cognitive schema in individuals with major depressive disorder. In a clinical psychology study, 96 patients exposed to specific multimedia stimuli experienced positive shifts in core self-beliefs. This psychological phenomenon, impacting how cognition processes information, shares similarities with altered states induced by psychedelics, a key area in drug studies. Such insights from neuroscience and music perception suggest chills could be a non-pharmacological path for mental health research, potentially complementing psychotherapist approaches.

Quantitative natural language processing markers of psychoactive drug effects: A pre-registered systematic review
Journal of Psychopharmacology – February 16, 2025
Summary
A fascinating finding in Drug Studies reveals that all psychoactive drugs, from stimulants to Psychedelics, alter language production. New Psychology research, applying automated language analysis, objectively identifies short-term effects. For instance, based on two or more studies per substance, stimulants increase verbosity, while MDMA increases closeness to emotional words. Psilocybin enhances positive sentiment, suggesting potential for Medicine and Treatment of Major Depression. One study even validated identifying MDMA intoxication. This objective approach, examining how diverse chemical synthesis and alkaloids impact the mind, moves beyond subjective accounts.

Reappraisal of the hype and hope offered by psilocybin treatment of depression
New Zealand Medical Journal – September 15, 2025
Summary
Early findings suggest psilocybin holds promise for depression, a significant area in Psychology and Mental Health. However, a review of Psychedelics and Drug Studies reveals methodological challenges like expectation bias. While generally well tolerated, side effects are often not systematically reported, and some recipients may experience harm. Comparing with ketamine for treatment-resistant depression shows similar issues, but ketamine's positive evidence is currently stronger. Therefore, the current data on psilocybin's efficacy and safety in Psychotherapy Techniques and Applications is insufficient to warrant wider availability for depression treatment.
