Reviewing the Reserve Supply of Immature Neurons in the Adult Brain

To what degree can the adult brain restructure and regenerate itself? In one sense the components of the central nervous system, brain included, are clearly among the least regenerative of tissues in mammalian species. In another sense the brain is capable of significant compensatory change following damage. Further, the normal operation of the brain over time depends upon the plasticity of neural circuits in response to changing circumstances: learning, memory, and so forth. The authors of today’s open access research propose that these capacities for regeneration and change may arise not just from a supply of daughter cells created by neural stem cell populations, but also from a reserve population of immature neurons that are generated during early development and then retained throughout life. This hypothesis lacks
