An Update on Non-CB1, Non-CB2 Cannabinoid Related G-Protein-Coupled Receptors Paula Morales and Patricia H. Reggio Cannabis and Cannabinoid Research, 2017, Volume 2.1, 265-273 DOI: 10.1089/can.2017.0036 Abstract The endocannabinoid system (ECS) has been shown to be of great importance in the regulation of numerous physiological and pathological processes. To date, two Class A G-protein-coupled receptors (GPCRs) have been discovered and validated as the main therapeutic targets of this system: the cannabinoid receptor type 1 (CB1), which is the most abundant neuromodulatory receptor in the brain, and the cannabinoid receptor type 2 (CB2), predominantly found in the immune system among other organs and tissues. Endogenous cannabinoid receptor [...]

Vaccarino Journal of The Royal Society, Interface, 2014, 11, 20140873 Published : 06 December 2014 https://doi.org/10.1098/rsif.2014.0873 Abstract Networks, as efficient representations of complex systems, have appealed to scientists for a long time and now permeate many areas of science, including neuroimaging (Bullmore and Sporns 2009 Nat. Rev. Neurosci.10, 186–198. (doi:10.1038/nrn2618)). Traditionally, the structure of complex networks has been studied through their statistical properties and metrics concerned with node and link properties, e.g. degree-distribution, node centrality and modularity. Here, we study the characteristics of functional brain networks at [...]

Griffiths The following chapter will appear in the Springer text “Behavioral Neurobiology of Psychedelic Drugs”, in the series “Current Topics in Behavioral Neuroscience” that is edited by Adam L Halberstadt, Franz X Vollenweider, and David E Nichols Current Topics in Behavioral Neuroscience, 2017 March 26. DOI: 10.1007/7854_2017_474 Abstract This chapter begins with a brief review of descriptions and definitions of mystical-type experiences and the historical connection between classic hallucinogens and mystical experiences. The chapter then explores the empirical literature on experiences with classic hallucinogens in which claims about mystical or religious experiences [...]

CARHART-HARRIS Neuroscience of Consciousness, 2019, 5, (1), niz003 doi: 10.1093/nc/niz003 Abstract Based on its ability to increase brain complexity, a seemingly reliable index of conscious level, we propose testing the capacity of the classic psychedelic, psilocybin, to increase conscious awareness in patients with disorders of consciousness. We also confront the considerable ethical and practical challenges this proposal must address, if this hypothesis is to be directly assessed. Key words : disorders of consciousness; psychedelics; psilocybin; complexity Introduction Disorders of consciousness (DoC) are the most devastating form of impairment that may follow acquired brain injury.

Lire la suiteThe Mechanisms of Psychedelic Visionary Experiences: Hypotheses from Evolutionary Psychology Michael J. Winkelman Frontiers in Neuroscience, 2017, 11, article 539, 1-17. doi: 10.3389/fnins.2017.00539 Neuropharmacological effects of psychedelics have profound cognitive, emotional, and social effects that inspired the development of cultures and religions worldwide. Findings that psychedelics objectively and reliably produce mystical experiences press the question of the neuropharmacological mechanisms by which these highly significant experiences are produced by exogenous neurotransmitter analogs. Humans have a long evolutionary relationship with psychedelics, a consequence of psychedelics’ selective effects for human cognitive abilities, exemplified in the information rich visionary experiences. Objective evidence that psychedelics produce classicmystical experiences, coupled [...]
Lire la suiteSalvinorin A, a kappa-opioid receptor agonist hallucinogen : pharmacology and potential template for novel pharmacotherapeutic agents in neuropsychiatric disorders Eduardo R. Butelman and Mary Jeanne Kreek Frontiers in Pharmacology, 2015 doi: 10.3389/fphar.2015.00190 Salvinorin A is a potent hallucinogen, isolated from the ethnomedical plant Salvia divinorum. Salvinorin A is a selective high efficacy kappa-opioid receptor (KOPr) agonist, and thus implicates the KOPr system and its endogenous agonist ligands (the dynorphins) in higher functions, including cognition and perceptual effects. Salvinorin A is the only selective KOPr ligand to be widely available outside research or medical settings, and salvinorin A-containing products have undergone frequent nonmedical use. KOPr/dynorphin [...]
