After a challenging day at work or school, sometimes it may seem like you are down to your last brain cell. But have no fear—in actuality, the brains of humans and other mammals have the potential to produce new neurons throughout life. This remarkable ability is due to a specific type of cell—adult neural stem cells—so beautifully highlighted in this award-winning micrograph.

Here you see the nuclei (purple) and arm-like extensions (green) of neural stem cells, along with nuclei of other cells (blue), in brain tissue from a mature mouse. The sample was taken from the subgranular zone of the hippocampus, a region of the brain associated with learning and memory. This zone is also one of the few areas in the adult brain where stem cells are known to reside.
