Human minibrains reveal effects of psychedelic substance
A Brazilian study, published in Scientific Reports on October 09, 2017, has identified changes in signaling pathways associated with neural plasticity, inflammation and neurodegeneration triggered by a compound from the family of dimethyltryptamine known as 5-MeO-DMT.
The study brings first evidence that psychedelics interfere with molecular signaling related to learning and memory in the human brain tissue. Minibrains, also known as cerebral organoids, have been considered a breakthrough in neuroscience studies.
