A single injection of the psychedelic compound 5-MeO-DMT into the brain's fluid-filled spaces increased the production of new neurons in the dentate gyrus of adult mice. Treated mice had more newborn granule cells, and these cells developed more complex branch-like structures. The new neurons also showed shorter afterhyperpolarization potentials and higher action potential thresholds, indicating altered electrical properties. These effects on neurogenesis may help explain the potential antidepressant actions of DMT-like compounds.
