Synergistic, multi-level understanding of psychedelics: three systematic reviews and meta-analyses of their pharmacology, neuroimaging and phenomenology

mycolabadmin

This comprehensive study analyzed three classic psychedelic drugs—LSD, psilocybin (from magic mushrooms), and DMT—across three levels: how people experience them, how they affect brain activity, and how they interact with brain receptors. Researchers found that LSD produces more intense visual experiences than psilocybin, and all three drugs significantly alter brain connectivity patterns. The study highlights the importance of standardizing research methods to better understand how these compounds might help treat depression and addiction.

Meditation, psychedelics, and brain connectivity: A randomized controlled resting-state fMRI study of N,N-dimethyltryptamine and harmine in a meditation retreat

mycolabadmin

Researchers studied how meditation combined with a psychedelic compound called DMT affects the brain. They scanned 40 experienced meditators before and after a 3-day retreat, with some receiving the psychedelic and others a placebo. While meditation alone reduced connections between different brain networks, the psychedelic enhanced certain connections, suggesting the two practices may complement each other in promoting mental health.

Transient destabilization of whole brain dynamics induced by N,N-Dimethyltryptamine (DMT)

mycolabadmin

This study used computer models of brain activity to understand how the psychedelic drug DMT rapidly changes how the brain works during an acute experience. Researchers found that DMT pushes brain dynamics into a special state where the brain becomes hypersensitive to small changes or stimuli. This heightened sensitivity is strongest in brain regions rich in serotonin receptors and matches the expected timing of the drug’s effects, suggesting that brief psychedelic experiences may create lasting changes in the brain through this temporary destabilization window.

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

mycolabadmin

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.

N,N-dimethyltryptamine effects on connectome harmonics, subjective experience and comparative psychedelic experiences

mycolabadmin

Researchers studied how DMT, a powerful psychedelic drug, changes brain activity patterns and how these changes relate to what people experience. Using advanced brain imaging and network analysis, they found that DMT shifts brain activity away from large-scale network patterns toward smaller, more diverse patterns. Importantly, these brain changes directly tracked with how intensely participants reported experiencing the drug’s effects moment-to-moment.

Adaptation and latent structure of the Brazilian version of the Ego Dissolution Inventory (EDI-BR): an exploratory study

mycolabadmin

This study adapted a psychological assessment tool called the Ego Dissolution Inventory for use in Brazil. Ego dissolution refers to the profound sense of losing one’s sense of self that people experience when using psychedelics like psilocybin mushrooms and LSD. The researchers found that the adapted Brazilian version works well and identifies three dimensions of the experience: confidence/assertiveness, ego dissolution, and ego inflation. This validated tool can now help researchers in Brazil better understand psychedelic experiences and their potential therapeutic benefits.
