Serotonin and brain function : a tale of two receptors, RL Carhart-Harris and DJ Nutt, 2017

Serotonin and brain function : a tale of two receptors RL Carhart-Harris and DJ Nutt Journal of Psychopharmacology, 2017, Vol. 31, (9), 1091–1120. Doi : 10.1177/0269881117725915   Abstract Previous attempts to identify a unified theory of brain serotonin function have largely failed to achieve consensus. In this present synthesis, we integrate previous perspectives with new and older data to create a novel bipartite model centred on the view that serotonin neurotransmission enhances two distinct adaptive responses to adversity, mediated in large part by its two most prevalent and researched brain receptors: the 5-HT1A and 5-HT2A receptors. We propose that passive coping (i.e. tolerating a source of stress) [...]

The Impact of Cannabidiol on Human Brain Function : A Systematic Review, Albert Batalla et al., 2021

The Impact of Cannabidiol on Human Brain Function : A Systematic Review Albert Batalla, Julian Bos, Amber Postma and Matthijs G. Bossong Frontiers in Pharmacology, January 2021 | Volume 11 | Article 618184, 1-15. doi : 10.3389/fphar.2020.618184   Background : Accumulating evidence suggests that the non-intoxicating cannabinoid compound cannabidiol (CBD) may have antipsychotic and anxiolytic properties, and thus may be a promising new agent in the treatment of psychotic and anxiety disorders. However, the neurobiological substrates underlying the potential therapeutic effects of CBD are still unclear. The aim of this systematic review is to provide a detailed and up-todate systematic literature overview of neuroimaging studies [...]
