Editorial: Generation of Neurons and Their Integration in Pre-existing Circuits in the Postnatal Brain: Signalling in Physiological and Regenerative Contexts

摘要

During the development of the nervous system, the production of hundreds of subtypes ofneurons and glial cells relies upon the relatively fast generation, amplification, specification,and differentiation of neural progenitors and neural stem cells (NSCs). This strategy, althoughrestricted, is retained in specific niches in the adult nervous system throughout lifetime underphysiological conditions. Furthermore, damage to the neural tissue in certain circumstancestriggers neurogenesis leading to regeneration.
