Acute serotonin 2A receptor activation impairs behavioral flexibility in mice.
Behavioural brain research – October 01, 2020
Summary
Activating 5-HT(2A) serotonin receptors impairs behavioral flexibility. Male mice performing probabilistic reversal learning required more trials to adapt when given a selective 5-HT(2A) agonist (25CN-NBOH, 1.0 mg/kg). While another agonist (DOI) alone had no effect, combining it with a 5-HT(2C) antagonist (SER-082, 1.0 mg/kg) similarly increased trials to criterion. This demonstrates 5-HT(2A) activation hinders probabilistic reversal learning, and 5-HT(2A) and 5-HT(2C) receptors exert opposing impacts on behavioral flexibility.

Over 112,000 Oregon residents and $1.2 million funded a ballot initiative to legalize psilocybin for psychiatric conditions. This political science effort, the first of its kind, faces strong opposition from psychiatry and medicine. While psychedelics show potential, with psilocybin in Phase 2 trials for depression, medical groups argue widespread use through a ballot bypasses crucial FDA safety and efficacy reviews. They emphasize that psychology and drug studies must guide treatment, not public vote, especially given the lack of medical oversight for vulnerable patients.

Drugs in therapy. LSD, MDMA, marijuana, psilocybin, designer drugs and its potential in modern medicine.
Farmacja Polska – September 28, 2020
Summary
Decades after research was delegalized, the pharmacology of certain drugs is revolutionizing psychiatry. Psilocybin and Lysergic acid diethylamide, once categorized as hallucinogens, show promise for anxiety, depression, and addiction. MDMA (Ecstasy) is proving effective for PTSD and autism-related social fears. Even designer drugs are being explored as potential medicine. These drug studies highlight a powerful new frontier in medicine, challenging historical views on psychedelics.
Abstract

N,N-dimethyltryptamine compound found in the hallucinogenic tea ayahuasca, regulates adult neurogenesis in vitro and in vivo
Translational Psychiatry – September 28, 2020
Summary
DMT, a key component of ayahuasca, significantly boosts neurogenesis in the subgranular zone of the dentate gyrus within the hippocampus. In a study involving mice, DMT administration led to a 30% increase in newly generated neurons compared to untreated controls. These mice also excelled in memory tasks, indicating that DMT enhances cognitive function through increased neural stem cell proliferation and neuroblast migration. The neurogenic effects are linked to sigma-1 receptor activation, suggesting potential therapeutic applications in neuroscience and neuropharmacology.

Neuromeditation: The Science and Practice of Combining Neurofeedback and Meditation for Improved Mental Health
Smart Biofeedback - Perspectives and Applications – September 28, 2020
Summary
Brain training meets mindfulness: New research shows combining EEG feedback with meditation can help people achieve deeper states of focus and relaxation in less time. By monitoring real-time brainwave patterns, practitioners receive instant feedback about their mental state, helping them recognize and maintain desired meditation states. This approach shows promise for treating anxiety, ADHD, and PTSD by teaching patients to better regulate their mental states.
Abstract
Beginning meditators often complain that they do not know if they are “doing it right” or give up before realizing significant benefits. Advanced m...
Pharmacokinetics and Pharmacodynamics of Lysergic Acid Diethylamide Microdoses in Healthy Participants
Clinical Pharmacology & Therapeutics – September 25, 2020
Summary
Lysergic acid diethylamide "microdosing" has a psychotropic threshold of 10 µg. A placebo-controlled Pharmacology study with 23 healthy participants explored the Pharmacokinetics and Pharmacodynamics of this synthetic alkaloid. While 5 µg of LSD showed no acute subjective effects, 10 µg significantly increased feelings of being "under the influence" and "good drug effect," peaking around 2.5 hours. LSD concentrations dose-proportionally increased, with a 2.7-hour elimination half-life. These Psychedelics and Drug Studies findings are crucial for developing LSD as a potential Medicine, informing Complementary and Alternative Medicine Studies.
