Psychedelics have received considerable attention due to their potential in treating psychiatric disorders. The "setting" during psychedelic-assisted therapy (PAT) is recognized as playing a central role in the experience, during which music features prominently. Although music is theorized as directing and shaping psychedelic sessions, its precise contribution to acute experience and...
The impact of classic psychedelics (5-HT2A receptor agonists) on personality traits has been studied for decades, and it has been hypothesized that the mechanisms underlying these changes are linked to agonism at cortical serotonergic 5-HT2A receptors. However, research results are contradictory. Therefore, the present paper aims to systematically evaluate the effects of psychedelics on...
Despite renewed investigations into classical psychedelic compounds, their pharmacokinetic profiles remain incompletely understood. This systematic review collated data from healthy adult volunteers on the pharmacokinetic properties of lysergic acid diethylamide (LSD), psilocybin, dimethyltryptamine (DMT), mescaline, and 5-methoxy-N,N-dimethyltryptamine (5-MEO-DMT). We identified 32 eligible...
Serotonergic psychedelics are increasingly investigated as treatments for affective disorders. Concerns persist regarding their potential to induce hypomania or mania, particularly in individuals with bipolar spectrum vulnerability. Whether these substances precipitate transient mood switches or contribute to persistent bipolar illness or diagnostic transition remains unclear. We conducted a...
A medição e quantificação precisas da consciência humana permanecem um dos desafios mais significativos na neurociência e física modernas. As Interfaces Cérebro-Computador (ICCs) tradicionais focam na decodificação de intenções motoras localizadas, tratando o cérebro como um gerador de comandos isolado. Baseando-se no conceito de Schrödinger de vida como organização informacional, no Princípio...
Mescaline, a 5-HT2A agonist psychedelic used ceremonially for millennia, lacks neuroimaging characterization due to its Schedule 1 status. Using pharmacological and resting-state fMRI in awake rats, we report mescaline's first comprehensive neurobiological profile. Acutely, mescaline produced cerebellar-selective BOLD suppression, suggesting functional disconnection from forebrain structures....
Abstract Paradoxically, psychedelics have long been used as models of both psychosis and therapy. After proposing mystical experiences as a link between these models for lysergic acid diethylamide (LSD), we aimed to extend and refine this framework for N,N -Dimethyltryptamine (DMT). In a randomised, placebo-controlled, double-blind, crossover study, 25 healthy participants received DMT (60mg)...
This chapter is designed to offer a comprehensive overview of five core psychedelic medicines—ketamine, psilocybin, MDMA, LSD, and ayahuasca—highlighting their distinct pharmacological properties, cultural origins, therapeutic applications, and clinical research. Although each substance offers a unique entry point into expanded states of consciousness, they share a common potential to catalyze...
As the cultural, scientific, and legal landscape surrounding psychedelics continues to shift toward greater access and acceptability, it is likely that increasing numbers of women of reproductive age may be exposed to these substances. Despite this, the evidence on antenatal exposure has not been systematically reviewed. To synthesize the human literature on child and maternal outcomes...
Recent studies show that psychedelics such as psilocybin and LSD can reliably occasion spiritual or “mystical-like” experiences under supportive conditions, and the spiritual dimension of these experiences may contribute to their reported mental health benefits. Scholars have begun exploring how such experiences might relate to spiritual growth within Christian frameworks, but most theological...
