This review looks at studies about classic psychedelics (like LSD, psilocybin, and DMT/ayahuasca) and their effects on neuroplasticity — the brain’s ability to change. Animal studies show these drugs can raise genes tied to plasticity and cause dendrite and synapse growth. Human results are mixed, especially when studies use blood…
This review looked at many studies about classic psychedelics (like psilocybin and LSD), MDMA, ketamine, and plant medicines (like ayahuasca). The authors explain how these drugs can change the brain’s wiring, calm inflammatory processes, and shift key brain chemicals. Those actions may help explain why small clinical trials and animal…
This paper suggests a new way to study how psychedelic-assisted psychotherapy (PAP) might work. The authors propose that psychedelics could put the adult brain into a state similar to developmental "critical periods," times when the brain is highly sensitive to experience. They recommend using a well-studied visual system model (ocular…
This review explains that classical serotonergic psychedelics — drugs like psilocybin, DMT (in ayahuasca), LSD, and ibogaine — can change brain cells and connections in lab and animal studies. These drugs have been shown to help neurons grow new branches and form more synapses, which are the contact points where…
This paper is a review of recent research on psychedelic drugs. The authors say some clinical trials show these drugs can help people with post-traumatic stress disorder, substance abuse problems, and depression that has not improved with other treatments. But scientists do not yet understand all the biological ways these…
This review looks at how psilocybin mushrooms and their active ingredient psilocin might affect the brain and mental health. The authors say that brain inflammation seems to play a role in many cases of depression and anxiety. Lab and clinical studies show that psilocin can lower brain inflammation, boost the…
Researchers pooled results from 29 human studies that measured blood levels of a protein called brain-derived neurotrophic factor, or BDNF, after people received so-called psychoplastogen drugs such as ketamine or psychedelics. They found no clear change in blood BDNF after these drugs. The authors say this does not prove the…
This paper reviews research on ayahuasca and its main ingredient, DMT, and how they might help with mental health. Ayahuasca is a plant brew that makes DMT work when you drink it because it also contains chemicals that stop the body from breaking DMT down. Lab studies and a small…
