Psychedelics and Neuroplasticity: A Systematic Review Unraveling the Biological Underpinnings of Psychedelics

mycolabadmin

This review examines how psychedelic substances like psilocybin and LSD affect brain structure and function. Research shows these compounds can increase BDNF (a protein crucial for brain health) and promote the growth of new neurons and connections between brain cells. These biological changes may explain why psychedelics have shown promise in treating depression and anxiety, with effects lasting weeks after a single dose.

Psychedelic-Assisted Therapy: Potential Benefits and Challenges in Mental Health Treatment

mycolabadmin

This review examines how psychedelic substances like psilocybin and MDMA, when combined with professional psychotherapy, show promise in treating difficult-to-treat mental health conditions including depression, PTSD, and anxiety. While early research suggests these substances could help in cases where conventional treatments have failed, the evidence is still preliminary and limited by small study sizes. Psychedelics appear to work by changing how the brain processes information and memories, though much more rigorous research is needed before they can be considered standard treatments.

Meta-correlation of the effect of ketamine and psilocybin induced subjective effects on therapeutic outcome

mycolabadmin

This study examined whether the psychological experiences people have while taking ketamine or psilocybin—such as feeling disconnected or having spiritual insights—are actually responsible for their mental health improvements. Researchers analyzed 23 studies and found that these subjective experiences explain about 10% of ketamine’s benefits and 24% of psilocybin’s benefits. Psilocybin’s effects appear more connected to therapeutic outcomes than ketamine’s, and both drugs showed stronger connections between subjective effects and treatment success in substance use disorder compared to depression.

Enhanced visual contrast suppression during peak psilocybin effects: Psychophysical results from a pilot randomized controlled trial

mycolabadmin

Researchers studied how psilocybin affects the way our visual system processes contrast and surrounding visual information. Participants completed vision tests after taking psilocybin or placebo, and the results showed that psilocybin made people more influenced by surrounding visual elements when judging the brightness of objects. Interestingly, the stronger the visual effects people experienced from psilocybin, the more their perception was influenced by these surroundings. This finding might help explain how psilocybin affects mood and could help scientists better understand depression and other conditions affecting vision.

How to account for hallucinations in the interpretation of the antidepressant effects of psychedelics: a translational framework

mycolabadmin

Psychedelic drugs like LSD and psilocybin show promise in treating depression with effects lasting months after single doses. However, scientists debate whether the hallucinations and mystical experiences these drugs produce are necessary for their healing effects. This review proposes a framework to test whether lower doses without hallucinations might still provide antidepressant benefits, similar to how anesthesia-administered ketamine works without the patient’s awareness.

Are Side Effects Necessary for Antidepressive Treatment: The Psilocybin Experience

mycolabadmin

Researchers are studying psilocybin (a compound from certain mushrooms) as a potential treatment for depression. However, there is debate about whether the hallucinogenic side effects are necessary for its therapeutic benefits. This paper argues that new research suggests the antidepressant effects work through specific brain pathways (serotonin, opioid, and glutamate systems) that don’t require hallucinations. The author suggests developing safer, non-hallucinogenic antidepressants that maintain the same therapeutic benefits.

A Review of Synthetic Access to Therapeutic Compounds Extracted from Psilocybe

mycolabadmin

Scientists have discovered that magic mushrooms contain compounds called psilocybin and psilocin that show promise in treating depression and other psychiatric conditions. However, extracting enough of these compounds from mushrooms is difficult, so chemists have developed multiple ways to synthesize them in laboratories. This review examines different chemical and biological methods for producing these therapeutic compounds, from traditional synthesis techniques to modern approaches using special catalysts and enzymes, making these medicines more accessible for clinical research.

Synthesis and bioactivity of psilocybin analogues containing a stable carbon–phosphorus bond

mycolabadmin

Researchers created new chemical versions of psilocybin (the active compound in magic mushrooms) that cannot be broken down by the body’s natural enzymes in the same way. They tested these new compounds to see if they could help with depression and anxiety by targeting specific brain receptors. The best compound worked well on the intended brain receptors but importantly showed less activity on a heart-related receptor, potentially making it safer than natural psilocybin.

Hype or hope? Ketamine for the treatment of depression: results from the application of deep learning to Twitter posts from 2010 to 2023

mycolabadmin

Researchers analyzed over 18,000 Twitter posts from 2010 to 2023 to understand what the public thinks about using ketamine to treat depression. They found that public opinion became much more positive after the FDA approved ketamine as a depression treatment in 2019. Most discussions consisted of personal stories from people who found ketamine helpful, especially those whose depression didn’t respond to other medications. While some people expressed caution and concerns, overall the public seems hopeful about ketamine’s potential.

Global species diversity and distribution of the psychedelic fungal genus Panaeolus

mycolabadmin

This study is a comprehensive catalog of 77 Panaeolus mushroom species worldwide, of which 20 are known to be hallucinogenic and contain psilocybin. Researchers found that these mushrooms are most commonly documented in Asia, South America, and Europe, but many regions have little to no research data. The review highlights significant gaps in our knowledge about where these species exist and which ones truly contain psychoactive compounds, information that is crucial as these fungi become legal in more countries for medical use.
