An ontology of psychedelic entity experiences in evolutionary psychology and neurophenomenology, Michael J. Winkelman, 2018

An ontology of psychedelic entity experiences in evolutionary psychology and neurophenomenology Michael James WINKELMAN Journal of Psychedelic Studies, 2018. Doi : 10.1556/2054.2018.002   Background and aims : Psychedelic entity experiences are examined from perspectives of evolutionary psychology and neurophenomenology. Their similarities with other entity experiences illustrate the need for a general biological explanation of entity experiences. Mechanisms are proposed to involve innate modules, operators, and intelligences that underlie ordinary cognitive inferences and provide the basis for supernatural thought. Methods : Comparisons of ayahuasca and dimethyltryptamine (DMT) entity experiences with other types of entity experiences show their fundamental similarities to conceptions of spirit guides, mythological beings, divinities, [...]

Henri Michaux et les gouffres (à propos de l’expérience mescalinienne), François Emmanuel, 2007

Henri Michaux et les gouffres (à propos de l’expérience mescalinienne) François Emmanuel   « Moi n’est jamais que provisoire » (Plume). « J’écris pour me parcourir… » annonçait Henri Michaux. À l’hiver 1954 (il a cinquante-cinq ans) il a amplement parcouru le monde, descendu en pirogue un affluent de l’Amazone, promené son étrangeté en Inde, en Chine, en Malaisie…, ramené de ces pays lointains des notations buissonnières, éparses, décalées, des fables drolatiques. Çà et là il s’est fait entomologiste fantasque ou zoologiste d’animaux fantastiques. Toujours curieux de l’ailleurs mais toujours un peu déçu, il a délaissé ces contrées réelles pour d’autres imaginaires, s’est lancé [...]

Single Shot of Ketamine May Herald 'Last Call' for Problem Drinking Deborah Brauser Medscape, December 11, 2019 Medscape Medical News © 2019 https://www.medscape.com/viewarticle/922460?src=wnl_tp10n_200116_mscpedit&uac=292598PZ&impID=2238619&faf=1   An experimental treatment that includes a single infusion of ketamine may lead to long-term improvement in problem drinking, new research suggests. In an study of 90 heavy drinkers, those who received a single dose of intravenous (IV) ketamine plus cognitive behavioral therapy (CBT) that focused on reactivating drinking-related "maladaptive reward memories" (MRMs) significantly curbed the urge to drink and reduced alcohol intake  compared with those who received the ketamine alone or a placebo infusion. In addition, the combination group reduced their average weekly alcohol consumption by [...]

Translational evidence for ayahuasca as an antidepressant : what’s next ? Rafael Guimaraes dos SANTOS, José Carlos BOUSO British Journal of Psychiatry, 2019, 41, (4), 275-276. Doi : 10.1590/1516-4446-2019-4104   Depression is among the most important contributors to global disability and suicidal deaths. Available antidepressants are usually selective inhibitors of serotonin and norepinephrine uptake, which need weeks of daily intake before therapeutic effects appear, have limited efficacy for many patients, and induce significant adverse reactions after prolonged use. Therefore, recent research has focused on finding new antidepressant compounds that are fast-acting, more effective, and less toxic. The article recently published by da Silva et al. in the [...]
