New neurons are formed in the brain well into old age — but this stops in Alzheimer’s

This is an exciting new twist on neurogenesis.

The E150 macaque hippocampus has many Ki-67+ cells in the SGZ as well as vimentin+ fibres and DCX+ cells between the dNE and the GCL (arrow). b, Toluidine- blue-stained semi-thin sections of the macaque DG reveal small and dark condensed nuclei (arrows) in the SGZ from fetal ages (E150) to 1.5 years; few are visible in the DG at 7 years of age and these cells are very rare in the DG of a 23-year-old macaque (compare with human data in Extended Data Fig. 2a).

We can’t grow new neurons in adulthood after all, new study says

byFrancesca Schiopca

Neurogenesis fully stops after the age of thirteen, researchers suggest.
