The increasing interest in the therapeutic potential of psychedelics and cannabis underscores the need to understand their long-term neuropsychological and personality effects. This cross-sectional study compared regular users of ayahuasca (n = 69), cannabis (n = 56), and non-substance users (n = 94) on a battery of neuropsychological tasks and psychological questionnaires. Participants were...

Em um contexto marcado pelo aumento do uso de drogas psiquiátricas como estratégia de enfrentamento das demandas cotidianas, observa-se maior prevalência entre mulheres, em razão dos papéis de gênero que lhes atribuem múltiplas funções em uma sociedade orientada pelo desempenho contínuo (Alvarenga; Dias, 2021). Esse cenário contribui para a medicalização progressiva de comportamentos cotidianos...
The main idea for Jakob Meløe is that our concepts originate in what we do: a toddler's expressions come from the lifeworld and environment of a toddler, and a fisherman's concepts originate in the practice of fishing and a life of seafaring. In this way words are related to a certain practice, but also to a certain place. The landscape that we call home reverberates with our concepts, through...
ABSTRACT What is the temporal structure of conscious experience? While it is popular to think that our most basic conscious experiences are temporally extended, we will be arguing against this view, on the grounds that it makes our conscious experiences depend on the future in an implausible way. We then defend an alternative view of the temporal structure of experience from a variety of...
Electroencephalography (EEG) recently celebrated its 100-year anniversary, having revolutionized the study of cognitive function across species. Over the past century, neuroelectric measures such as resting-state EEG, event-related potentials (ERP), and event-related oscillations (ERO) have become indispensable not only for advancing our understanding of brain function but also for identifying...
Background: Psilocybin treatment has shown promise across a range of psychiatric conditions. Mystical-type experiences during dosing sessions have been shown to predict the clinical effects of psilocybin treatment in depression, anxiety, and addiction. However, no studies have examined whether acute subjective experiences predict treatment response in obsessive-compulsive disorder (OCD)....
Mind body practices like meditation and yoga, which are widely used to support mental health, involve paying attention to internal bodily sensations like the breath. During these practices, individuals often report "interoceptive lapses," moments when attention drifts away from the body. While lapses in attention to the external world have been widely studied, far less is known about...
The importance of drugs as a theme in the second half of Elsa Morante’s work is rarely emphasized. Beginning with the author’s existential and political turn in the 1960s, a decade that saw her experiment with a series of sedatives and psychedelics, drugs and addiction become omnipresent in the lives of some of the key characters in her novels and short stories. This article focuses on the...
3,4-methylenedioxymethamphetamine (MDMA) is a psychomotor stimulant drug. While much research has examined the effects of MDMA in adults, relatively little research has examined the effects in adolescents. Adolescence is a unique period of brain development, and the effects of MDMA may differ in adolescents compared to adults. In this review, we summarize the literature on the effects of acute...
The origin of consciousness remains one of the oldest problems in both science and philosophy. Several emerging theories provide new perspectives on the origin and evolution of consciousness, including Cellular Basis of Consciousness (CBC) theory and the Cognition-Based Evolution (CBE) theory. Moreover, declarations such as the New York Declaration on animal consciousness further underscore the...
