Steve White, Benjamin J. Whalley, Sarah Glyn, Haramrit Sandhu, Nicholas Jones, Michael Bazelot, Claire M. Williams, Alister James McNeish Epilepsia, 2018, 1–12. DOI: 10.1111/epi.14629 Summary Objective : Epilepsy is a progressive neurological disease characterized by recurrent seizures and behavioral comorbidities. We investigated the antiseizure effect of cannabidiol (CBD) in a battery of acute seizure models. Additionally, we defined the disease‐modifying potential of chronic oral administration of CBD on associated comorbidities in the reduced intensity status epilepticus–spontaneous recurrent seizures (RISE‐SRS) model of temporal lobe [...]

Lire la suiteA Sensory Ecology of Medicinal Plant Therapy in Two Amazonian Societies GLENN H. SHEPARD JR. American Anthropologist, 2004, Vol. 106, Issue 2, pp. 252–266, ISSN 0002-7294 ABSTRACT Sensory anthropology has explored sensation as a fruitful but poorly examined domain of cross-cultural research. Curiously, sensory anthropologists have mostly ignored scientific research into sensation, even that which addresses cross-cultural variation. A comparative study in two Amazonian societies (Matsigenka, Yora [Nahua]) documented the role of the senses in medicinal plant therapy and benefited greatly from theoretical insights gleaned from sensory science. The study reveals a complex interweaving of cultural and ecological factors in medicinal plant selection, with sensation [...]

Ces objectifs posent implicitement plusieurs problèmes fondamentaux, complexes, interdépendants, dont l’ampleur tient à la fois à l’importance des enjeux et au fait qu’ils concernent une grande partie de la population mondiale. Jusqu’à quel point [...]

Palamar & Austin Le Human Psychopharmacology Clinical and Experimental, 2019, e2690 DOI: 10.1002/hup.2690 Abstract Objectives : This study aims to examine patterns and first mentions of reported use of new or uncommon drugs across 13 years, among nationally representative samples in the United States. Methods : Participants (ages ≥12) in the National Surveys on Drug Use and Health (2005–2017, N = 730,418) were provided opportunities to type in names of new or uncommon drugs they had ever used that were not specifically queried. We examined self‐reported [...]

Pour contribuer à cette anthropologie la dissociation, je commencerai par l'étude de certaines pratiques chamaniques examinées du point de vue de la théorie de la conscience dissociée. J'examinerai ensuite la position qui consiste à rejeter cette analyse au motif [...]
Lire la suiteThe link between childhood trauma and dissociation in frequent users of classic psychedelics and dissociatives Sascha B. Thal, Judith K. Daniels & Henrik Jungaberle Journal of Substance Use, may 2019 https://doi.org/10.1080/14659891.2019.1614234 ABSTRACT Background : Childhood trauma severity is associated with the level of subsequent substance use as well as with the self-reported severity of dissociation. Classic psychedelics and dissociatives target neurotransmitter systems thought to be involved in the onset of dissociative symptoms and may evoke severe and long-lasting symptoms of depersonalization in some users. However, it is currently unclear whether drug use puts people with a history of childhood trauma at higher risk of developing [...]
