Adult Hippocampal Neurogenesis Is a Developmental Process Involved in Cognitive Development

摘要

All processes in the body of animals can be divided into three groups. Developmental processesare responsible for the formation of tissues and organs via the addition of new cells and theirdifferentiation into the proper cell types to ensure correct organ and tissue functionality. Adultprocesses are responsible for the maintenance of organ and tissue functionality, in part viathe replacement of burnout cells. And aging processes that are characterized by the declineof tissue and organ functionality, often coinciding with cell loss. There is no sharp boundarybetween these processes and they smoothly transfer from one into another. Adult hippocampalneurogenesis (AHN) in the mammalian brain appears to be a late developmental processsupported by neural transit cells (NTCs) that never advances into the adult process stage(Bonfanti, 2016; Lipp and Bonfanti, 2016).
