Neurogenesis is the process by which neurons are created. This process is most active during pre-natal development when neurogenesis is responsible for populating the growing brain.
Neural stem cells (NSCs) are the self-renewing, multipotent cells that differentiate into the main phenotypes of the nervous system. These cell types include neurons, astrocytes, and oligodendrocytes. Neural progenitor cells (NPCs) are the progeny of stem cell division that normally undergo a limited number of replication cycles in vivo.
