Unfortunately, the evidence examining its use in mental health has been slow to evolve, but is emerging. Given the widespread use of cannabis, it is important for both clinicians and those who suffer with anxiety to understand the effects of cannabis on symptoms of anxiety. In this review, we present [...]

Crippa, Jaime E.C. Hallak, Draulio B. de Araujo, Jordi Riba European Neuropsychopharmacology, 2015, 25, 483–492 http://dx.doi.org/10.1016/j.euroneuro.2015.01.008 Abstract Psychedelic agents have a long history of use by humans for their capacity to induce profound modifications in perception,emotion and cognitive processes. Despite increasing knowledge of the neural mechanisms involved in the acute effects of these drugs, the impact of sustained psychedelic use on the human brain remains largely unknown. Molecular pharmacology studies have shown that psychedelic 5-hydroxytryptamine (5HT)2A [...]

Nutt Psychopharmacology, 2014 DOI 10.1007/s00213-014-3714-z Abstract Rationale : Lysergic acid diethylamide (LSD) has a history of use as a psychotherapeutic aid in the treatment of mood disorders and addiction, and it was also explored as an enhancer of mind control.

LSD (40–80 μg) in a within-subject placebocontrolled design. Suggestibility and cued mental imagery were assessed using the Creative [...]
Lire la suiteThe mixed serotonin receptor agonist psilocybin reduces threat-induced modulation of amygdala connectivity Rainer Kraehenmann, André Schmidt, Karl Friston, Katrin H. Preller, Erich Seifritz, Franz X. Vollenweider NeuroImage : Clinical, 2016, 11, 53–60 http://dx.doi.org/10.1016/j.nicl.2015.08.009 a b s t r a c t Stimulation of serotonergic neurotransmission by psilocybin has been shown to shift emotional biases away from negative towards positive stimuli. We have recently shown that reduced amygdala activity during threat processing might underlie psilocybin's effect on emotional processing. However, it is still not known whether psilocybin modulates bottom-up or top-down connectivity within the visual-limbic-prefrontal network underlying threat processing.We therefore analyzed our previous fMRI data using [...]
