Images 1 and 2 (OB): A view inside the olfactory bulb of an adult mouse (the region of the brain that processes odor perception) in which neurons are red and neural helper cells called astrocytes are in green. While the creation of new neurons in the olfactory bulb generally declines with age, the Nature paper shows that deletion of the gene P16Ink4a partially rescues this age-related decline in neurogenesis.

This is a view of the forebrain of an adult mouse. Neurons are in red, neural helper cells called astrocytes are in green, and nuclei are in blue. Neural progenitor cells in this part of the forebrain give rise to new neurons throughout life but this neurogenesis declines with age. The Nature paper shows that deletion of the gene P16Ink4a partially rescues this age-related decline in neurogenesis. |
