Psilocybin and Neurogenesis: Can Magic Mushrooms Grow New Brain Cells?
Direct Answer: Emerging research suggests psilocybin may promote hippocampal neurogenesis — the growth of new neurons in the brain's memory and emotion center. This would represent a significant mechanism beyond the neuroplasticity effects already documented.
The Evidence
Animal studies show psilocybin promotes hippocampal neurogenesis. BDNF increase (psilocybin dramatically increases BDNF, which promotes neurogenesis). Sigma-1 receptor activation (associated with neuroprotection and neurogenesis).
Why This Matters
Depression, chronic stress, and aging all reduce hippocampal neurogenesis. If psilocybin promotes neurogenesis, it could explain some of its most durable antidepressant effects.

Does microdosing promote neurogenesis?
Animal studies suggest yes — microdose-level psilocybin promotes hippocampal neurogenesis. Human studies are underway.
