Adult neurogenesis is the production of new neurons in the adult brain from resident stem cell populations. In many species, including fish and birds, it is a common process, but in the mammalian brain it occurs at a small scale in only two specific regions: the olfactory bulb and the hippocampus. The process of adult neurogenesis is believed to be connected to higher cognitive functions including learning and memory, and therefore is an important therapeutic target within an aging society.
This poster, developed with Gerd Kempermann at the Center for Regenerative Therapies in Dresden, shows the different processes contributing to adult neurogenesis in the olfactory bulb and hippocampus of the adult brain.
