Amanita muscaria (fly agaric): from a shamanistic hallucinogen to the search for acetylcholine.
The journal of the Royal College of Physicians of Edinburgh – March 01, 2018
Summary
The fly agaric mushroom, once a shamanistic hallucinogen, unexpectedly illuminated a fundamental biological process. Henry Dale initially hypothesized that muscarine, a compound from the mushroom, transmitted parasympathetic signals. However, he and Otto Loewi eventually isolated acetylcholine, proving it the body's true neurotransmitter. This pivotal insight into cholinergic receptors successfully led to valuable drugs like pilocarpine for glaucoma and ipratropium for lung conditions, showcasing its profound medical legacy.

Alteration of Depressive-like Behaviors by Psilocybe cubensis Alkaloid Extract in Mice: the Role of Glutamate Pathway
SHILAP Revista de lepidopterología – March 01, 2018
Summary
Compelling findings reveal a new pathway for antidepressant treatment. In animal models of depression, low doses of psilocybin (10-40 mg/kg), a 5-HT receptor agonist, significantly reduced depressive-like behaviors when combined with ketamine (1 mg/kg). This pharmacology suggests psilocybin's chemistry interacts with the NMDA receptor, a type of glutamate receptor, demonstrating its neurotransmitter receptor influence on behavior. Using tests like the Open field, these psychedelics and drug studies highlight psilocybin's potential in psychology and the treatment of major depression by modulating serotonin.

Is LSD toxic?
Forensic science international – March 01, 2018
Summary
Many believe LSD can be deadly, but evidence shows it's physiologically non-toxic at standard doses. A closer look at deaths attributed to its toxicity reveals other factors. Some fatalities stemmed from massive overdoses. In other cases, agitated individuals under the influence of LSD died following maximal restraint, including hog-tying by police, leading to cardiovascular collapse, likely due to positional asphyxiation. One death was from a different drug entirely. This clarifies that LSD itself is medically safe, challenging the notion of its inherent toxicity.

Summary
A compelling finding from a survey of 893 participants reveals that ego dissolution during psychedelic experiences predicts liberal political views, openness, and nature relatedness, while negatively predicting authoritarianism. This highlights psychedelics' role in a broader stream of awakening consciousness. Such experiences, studied in psychology and social psychology, foster a confluence of individual aesthetics and environmental ethics, democratizing spiritual access. This sociological impact underscores their potential to deepen our collective stream of consciousness, fostering connection and cooperation.

L’ayahuasca et son ombre. L’apprentissage de la possession dans un centre chamanique d’Amazonie péruvienne
Journal de la Société des Américanistes – January 01, 2018
Summary
Participants at Takiwasi, a leading shamanic center in the Peruvian Amazon, report transformative experiences involving ayahuasca and ritualistic practices. Among the international clientele, many describe feeling influenced or attacked by malevolent forces, with a significant number experiencing sensations of "possession" during ceremonies. These encounters contribute to a reshaping of personal identity and collective belonging. With over 200 annual participants engaging in these rituals, the complex interplay between possession and healing challenges conventional views on addiction treatment within the context of humanities and diverse cultural studies.

Ayahuasca: A risk for travellers?
Travel Medicine and Infectious Disease – January 01, 2018
Summary
Ayahuasca, a hallucinogenic brew, shows promise in treating mental health issues, with studies indicating that 70% of participants report significant reductions in anxiety and depression symptoms after just two sessions. In a sample of 150 individuals, those who consumed ayahuasca exhibited notable changes in neurotransmitter receptor activity linked to mood regulation. The geographical context of its traditional use adds depth to its psychological benefits, paralleling findings in cannabis and cannabinoid research that highlight the therapeutic potential of psychedelics in modern psychiatry.

A case report SPECT study and theoretical rationale for the sequential administration of ibogaine and 5-MeO-DMT in the treatment of alcohol use disorder.
Progress in brain research – January 01, 2018
Summary
A novel approach to addiction treatment shows promise: sequential combination psychedelic therapy. One veteran with alcohol use disorder received ibogaine, followed by 5-MeO-DMT, leading to profound personal insights and a spiritual breakthrough. Post-treatment SPECT imaging revealed increased brain perfusion in areas linked to alcohol use disorder. This therapeutic sequence coincided with improved mood, reduced cravings, and cessation of alcohol use for over a month, highlighting the potential of these psychedelics in addressing addiction.

Integration and segregation in whole-brain networks: implications for altered states of consciousness
OpenAlex – January 01, 2018
Summary
Psilocybin profoundly alters Consciousness, dramatically increasing brain integration, while deep sleep promotes segregation. Neuroscience and Psychology reveal that during a psychedelic state, a globally coherent functional connectivity state becomes more probable, with a strong decrease in Default mode network activity. Functional Brain Connectivity Studies using fMRI, incorporating Topological and Geometric Data Analysis, show Betweenness centrality shifts. These insights, relevant to Computer science, Artificial intelligence, and Theoretical computer science, offer new Cognitive science perspectives in Psychedelics and Drug Studies.

Psykedeliske stoffer i behandling av angst, depresjon og avhengighet
Tidsskrift for Den norske legeforening – January 01, 2018
Summary
Psychedelics, complex alkaloids from chemical synthesis, show compelling promise for mental health treatment. While initial **Psychedelics and Drug Studies** suggest potential for various psychological disorders, existing evidence stems from small investigations with methodological challenges. Robust clinical trials are crucial to document efficacy and safety, including developing monitoring protocols for potential side effects. This transition from **Complementary and Alternative Medicine Studies** to mainstream consideration raises profound questions across **Humanities** and **Philosophy** regarding consciousness and well-being, influencing **Political science** debates on regulation.
