Oh Excellent Air Bag presents a curated collection of 12 scientific and popular works about nitrous oxide, spanning 1799 to 1920. Voyeuristic readers will enjoy reading the frequently explicit experiences of inhaling nobles. Readers who prefer a coherent history with a focus on characters, causes, and effects may be less satisfied. That reader will savor the historian Mike Jay’s engaging...
The serotonin (5-HT) 2A receptor is the primary molecular target of serotonergic hallucinogens, which trigger large-scale perturbations of the cortex. Our understanding of how 5-HT2A activation may cause the effects of hallucinogens has been hampered by the receptor unselectivity of most of the drugs of this class. Here we used 25CN-NBOH...
This chapter argues that the case for a particular instance of experience to be illusory depends on how such an experience extends and is embedded in time and on how the constitution of experience allows or disallows naïve realism. It also argues for some conditions for illusion, hallucination, and anosognosia, and distinguishes between them. The chapter outlines the conditions of illusion. It...
Many individuals believe that meditation has the capacity to not only alleviate mental-illness but to improve prosociality. This article systematically reviewed and meta-analysed the effects of meditation interventions on prosociality in randomized controlled trials of healthy adults. Five types of social behaviours were identified: compassion, empathy, aggression, connectedness and prejudice....
: Novel psychoactive substance use is a major social concern. Their use may elicit or uncover unpredictably as yet undescribed clinical pictures. We aimed to illustrate a multisubstance use case indistinguishable from paranoid schizophrenia, so to alert clinicians on possibly misdiagnosing substance-induced psychotic disorders. CASE REPORT: We describe a case of a 32-year-old man who started at...
Selfhood is linked to brain processes that enable the experience of a person as a distinct entity, capable of agency. This framework naturally incorporates a continuum of both non-conscious and conscious self-related information processing, and includes a hierarchy of components, such as awareness of existence (core self), embodied self (sentience), executive self (agency/volition), and various...
To enable the impact of neuroscientific insights on our daily lives, careful translation of research findings is required. However, neuroscientific terminology and common-sense concepts are often hard to square. For example, when neuroscientists study lying to allow the use of brain scans for lie-detection purposes, the concept of lying in the scientific case differs considerably from the...
Background: Although numerous studies have demonstrated that mindfulness-based stress reduction (MBSR) improves clinical and nonclinical outcomes, few studies have followed MBSR participants for >12 months, and few have analyzed post-intervention home practice. Methods: We followed a community sample of 247 self-referred adults for 2 years after completion of an 8-week MBSR program. Dependent...
Chronic pain is estimated to occur in from 5.5% to 33% of the world's adult population (Gureje et al., 1998). Chronic pain is frequently treated with opiates, which has produced an opiate addiction crisis (Dowell et al., 2016). Several non-pharmacological treatment alternatives can help manage chronic pain. There is moderate evidence that mindfulness-based interventions (MBIs) such as...
Cannabis-related impairments to cognitive function may represent novel therapeutic targets for cannabis-use disorder, although the nature, persistence, and reversibility of such deficits remain unclear. Adult male rhesus monkeys (N = 6) responded in the morning on tasks designed to assess different cognitive domains using the Cambridge Neuropsychological Test Automated Battery (CANTAB)...
