New neurons, shown here in the mouse, are born throughout life in a specific region of the brain’s hippocampus. This region, known as the dentate gyrus, is involved in pattern separation, the ability to discriminate between very similar memories. Image credit: Winkle, et al. The Journal of Neuroscience, 2016.
Aerobic exercise like running can improve cognitive function in people, and one of the ways it may do this is by enhancing neurogenesis. Studies in mice show exercise boosts neurogenesis in the dentate gyrus of the hippocampus and this leads to improved learning and memory
