Adult Neurogenesis in Humans.
Level 5 - mechanism / opinion, no new human data
Narrative review without systematic methodology or primary human data reported
PubMed 26134318 · doi:10.1101/cshperspect.a018994
What was done
Narrative review examining quantitative findings and methodological developments regarding adult neurogenesis in humans compared to other mammals.
What was found
The abstract provides no numerical data. It reports that adult humans exhibit substantial hippocampal neurogenesis and continuous neurogenesis in the striatum, but lack detectable olfactory bulb neurogenesis.
Why it matters
It outlines distinct regional patterns of adult neurogenesis in humans, specifically highlighting striatal neurogenesis and the absence of olfactory bulb neurogenesis.
Limits
The abstract describes a narrative review without reporting primary sample sizes, methodology, or quantitative metrics.

- supports The adult human brain does not generate new neurons across most regions, producing only tiny numbers in areas such as the olfactory bulb and the dentate gyrus of the hippocampus.
