Hippocampal Neurogenesis Persists in Aging

humans we make new neurons in a specific brain region throughout our lifespan. This region, the hippocampus, and its new neurons, are necessary for emotional regulation and memory. In rodents, it has been shown that the generation of new neurons in the hippocampus declines dramatically after middle age. This phylogenetic difference may serve humans in sustaining their complex learning and emotion-guided decision-making through their long lifespan.
