BrdU/NeuN double-labeling to identify newly generated neurons in the granule cell layer of the mouse hippocampus. In the absence of injury (control), neurogenesis is several-fold higher in the younger (pnd 9) brains compared to at pnd 21. However, the response to hypoxia-ischemia (HI) is paradoxical-neurogenesis is decreased after injury at pnd 9, but increased in the pnd 21 injured brain. H: hypoxia only. Asterisks indicate statistical significance compared to age-matched controls. Modified from Qiu et al. (2007).
