Naturalistic psychedelic therapy: The role of relaxation and subjective drug effects in antidepressant response

mycolabadmin

Researchers studied how LSD and psilocybin work in real-world therapy settings in Switzerland. They found that these compounds effectively reduced depression symptoms in patients who hadn’t responded to other treatments. Surprisingly, the feeling of relaxation during the session was more important for improvement than having intense mystical experiences. The therapy was generally safe, with side effects that resolved quickly.

Exploring psychedelic use in athletes and their attitudes toward psilocybin-assisted therapy in concussion recovery

mycolabadmin

This study surveyed athletes and sports staff in Canada and the United States about their views on using psilocybin-assisted therapy to treat concussion symptoms. Researchers found that about 36% of athletes had used psychedelics in the past year, with psilocybin being the most common. Most athletes (61%) and staff (71%) said they would be willing to try or support psilocybin therapy for concussion recovery if research showed it was beneficial. The main factor influencing willingness was knowledge about psilocybin and positive attitudes toward it.

Transient Elevation of Plasma Glucocorticoids Supports Psilocybin-Induced Anxiolysis in Mice

This study examined how psilocybin works to reduce anxiety in mice by investigating the role of stress hormones, particularly corticosterone. Researchers found that psilocybin causes a temporary spike in corticosterone levels that is essential for its anxiety-reducing effects hours after administration. Interestingly, other interventions that increase corticosterone levels also produced similar anxiety-reducing effects, suggesting the stress hormone response itself drives the therapeutic benefit rather than psilocybin’s psychedelic properties alone. These findings suggest that measuring cortisol levels in human patients receiving psilocybin therapy could help explain and optimize therapeutic outcomes.

Network control energy reductions under DMT relate to serotonin receptors, signal diversity, and subjective experience

Researchers studied how DMT affects the brain’s ability to switch between different activity patterns. Using simultaneous brain imaging (fMRI) and electrical recordings (EEG), they found that DMT makes these transitions easier and less energy-intensive. The effects occurred primarily in brain regions with high levels of serotonin 2a receptors and were accompanied by increased complexity of brain signals and stronger subjective drug effects.

Sex-specific role of the 5-HT2A receptor in psilocybin-induced extinction of opioid reward

mycolabadmin

Researchers discovered that a single dose of psilocybin can reduce opioid addiction-related behaviors in male mice by activating serotonin receptors in specific brain circuits, but this effect does not work the same way in females. The study reveals that psilocybin changes how the brain processes opioid rewards and withdrawal symptoms, suggesting psychedelics could become a new treatment approach for opioid addiction. However, important sex differences in how the brain responds mean treatments may need to be tailored differently for men and women.
