Neurogenesis
Neurogenesis
(birth of
neurons
) is the process by which neurons are generated from
neural stem cells
and
progenitor cells
. It plays a central role in
neural development
. Neurogenesis is most active during
pre-natal development
and is responsible for populating the growing
brain
with neurons. In mammals,
adult neurogenesis
has been shown to occur in multiple brain structures, including the
dentate gyrus
of the
hippocampus
and the
olfactory bulb
.
