Abstract

New neurons continue to be generated in the subgranular zone of the dentate gyrus of the adult mammalian hippocampus. This process has been linked to learning and memory, stress and exercise, and is thought to be altered in neurological disease. In humans, some studies have suggested that hundreds of new neurons are added to the adult dentate gyrus every day, whereas other studies find many fewer putative new neurons. Despite these discrepancies, it is generally believed that the adult human hippocampus continues to generate new neurons. Here we show that a defined population of progenitor cells does not coalesce in the subgranular zone during human fetal or postnatal development. We also find that the number of proliferating progenitors and young neurons in the dentate gyrus declines sharply during the first year of life and only a few isolated young neurons are observed by 7 and 13 years of age. In adult patients with epilepsy and healthy adults (18-77 years; n = 17 post-mortem samples from controls; n = 12 surgical resection samples from patients with epilepsy), young neurons were not detected in the dentate gyrus. In the monkey (Macaca mulatta) hippocampus, proliferation of neurons in the subgranular zone was found in early postnatal life, but this diminished during juvenile development as neurogenesis decreased. We conclude that recruitment of young neurons to the primate hippocampus decreases rapidly during the first years of life, and that neurogenesis in the dentate gyrus does not continue, or is extremely rare, in adult humans. The early decline in hippocampal neurogenesis raises questions about how the function of the dentate gyrus differs between humans and other species in which adult hippocampal neurogenesis is preserved.

  • It is well accepted that neurogenesis sharply decreases in the aged mammalian nervous system, with no new neurons detectable in mice by 10 months of age.

    “It is well accepted that neurogenesis sharply decreases in the aged mammalian nervous system29–31, with no new neurons detectable in mice by 10 months of age29,31.”

    The paper’s Abstract reports a sharp early decline in hippocampal neurogenesis in humans and a decline during juvenile development in macaques. It does not report that no new neurons are detectable in mice by 10 months of age; that species-specific claim is unsupported by this source. (LLM, conf=0.88)

  • Some groups report absent or minimal hippocampal neurogenesis in the mature brain using double immunofluorescence and single nucleus transcriptomics.

    “Some groups have reported absent or minimal hippocampal neurogenesis in the mature brain using double immunofluorescence targeting markers expressed by neuronal cells at different maturational stages95, 96 and single nucleus transcriptomics97.”
  • Adult hippocampal neurogenesis appears to occur in humans as well as in rodents, although this idea is still controversial.

    “Adult hippocampal neurogenesis appears to occur in humans as well as in rodents, although this idea is still controversial (36, 37).”
  • The majority of reports provide positive evidence for adult neurogenesis in the human hippocampus, suggesting that studying this process in rodents is likely relevant to understanding human brain plasticity.

    “A few studies contradict these findings (Cipriani et al., 2018; Sorrells et al., 2018), but the majority of reports provide positive evidence for adult neurogenesis in the hippocampus of humans, suggesting that studying this process in rodents is likely relevant to understanding human brain plasticity.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
