IntroductionPain habituation, the reduction in response to repeated painful stimuli, is a positive adaptation process, while pain sensitization is linked to chronic pain. Traits like mindfulness and extraversion affect pain processing, but their influence on pain adaptation and potential interactions remains underexplored. This study aimed to examine the relationship between trait mindfulness,...

BACKGROUND Synthetic cannabinoids (SCs) are currently one of the most severely abused new psychoactive substances in the world. However, there remains a notable lack of pharmacological data on the newly emerged synthetic cannabinoids. In the present study, the in vitro and in vivo pharmacological effects of the fourth-generation synthetic cannabinoids 4F-ABUTINACA and SDB-005 are determined and...

AbstractIntroductionCannabis-induced psychosis (CIP) is often assumed to resolve with sustained abstinence, although recent studies report adverse long-term outcomes, such as a high risk of diagnostic transition to schizophrenia. Cannabis is also known to increase relapse rate in individuals with psychotic disorders in general, and there is a lack of knowledge on optimal treatment of this...

Most of us effortlessly describe visual objects, whether seen or remembered. Yet, around 4% of people report congenital aphantasia: they struggle to visualize objects despite being able to describe their visual appearance. What neural mechanisms create this disparity between subjective experience and objective performance? Aphantasia can provide novel insights into conscious processing and...

Interest in technology supporting meditation continues to grow commercially and academically. Commonly, these approaches look at how audio-visual feedback based on physiological indicators can help induce a state of meditation. Haptic feedback is now seen as a promising alternative to audio-visual stimuli for meditation. However, as yet, little work has investigated how to personalize haptic...

Abstract If a machine attains consciousness, how could we find out? In this paper, I make three related claims regarding positive tests of machine consciousness. All three claims center on the idea that an AI can be constructed “ad hoc”, that is, with the purpose of satisfying a particular test of consciousness while clearly not being conscious. First, a proposed test of machine consciousness...

HIV-associated neurocognitive impairment (NCI) is an untreated concern among people living with HIV (PLWH). Cannabis use in PLWH may complicate outcomes on cognition, with evidence to suggest function-dependent effects that are modulated by several factors including use patterns (e.g., frequency of use) and demographic influences (e.g., age). Animal studies can control for these factors. Here,...

Abstract Background: Substance-induced psychosis is an acute psychotic condition occurring after substance use, where the psychotic symptoms are alleviated with abstinence. Some of those diagnosed with substance-induced psychosis later develop schizophrenia, and this transition occurs most often for psychosis induced by cannabis. This talk will present results from a register-based study...

Psychedelic-assisted therapy could transform treating psychiatric illness, but harms from exacerbating substance use disorder (SUD) among adults with psychiatric illness using psychedelics have not been studied. A cross-sectional survey in the US was used to test whether Drug Abuse Screening Test scores (DAST-10, validated instrument predicting SUD) were more severe when psychiatric illnesses...
