Neurogenesis, the production of new neurons, primarily occurs in the dentate gyrus of the hippocampus and is not a prominent feature of learning and acquisition of new skills or experiences in the adult human brain, nor is it thought to occur as a consequence of psilocybin use.

“Neurogenesis in other regions of the adult human brain are exceedingly rare. And to be honest, may not occur at all. This is a debated area. We could do an entire episode about this. But for the most part, neuroscientists don't really believe that your neocortex, your striatum, your cerebellum has that much neurogenesis that's related to learning and memory of new things, or new experiences. And we don't actually think that occurs as a consequence of taking psilocybin either.”
