Professor Fred Gage explains that neurogenesis is an unstable process and is highly regulated by the environment.
One of the amazing things about neurogenesis is that it is not stable. It is highly regulated, so experience, behavioral experience, can affect the amount of neurogenesis that occurs. This can be divided into at least two categories. One is your physical interaction with your environment, so the physical motion can induce a proliferation of cells in the hippocampus, in the adult hippocampus. It looks like experiencing the environment, learning, acquiring information about the environment, also has some effect on survival. So, physical movement within your environment and acquisition, or learning, of information about your environment both have some effect on both the proliferation and the survival of these newly born cells in the brain - in the hippocampus in particular.

Professor Fred Gage explains that neurogenesis only occurs in the hippocampus and the olfactory bulb in humans, and discusses why this might be so.
Research continues to show that stem cells could be harnessed for therapeutic purposes.
Professor Fred Gage defines the key features of stem cells, which include self-renewal and the ability to give rise to another cell.
New neurons in the hippocampus may remember the timing of events.
Professor Fred Gage describes how he and his colleagues developed techniques to measure neurogenesis in human brain tissue.
Evidence in humans that a structured exercise training program increases neurogenesis.
Professor Ronald McKay explains that neurons in the hippocampus and olfactory bulb are unique in that they are produced throughout life. This is known as neurogenesis.
Mental retardation: struggle, stigma, science.
The dentate gyrus is one of the few regions in the brain where adult neurogenesis has been confirmed. It may play an important role in translating neural codes for creating memories.
Learning and memory are two intimately linked cognitive processes that stem from interactions with the environment (experience).
