Cellular Imaging and Emerging Technologies for Adult Neurogenesis Research

Abstract

The first report on the generation of new neurons in the adult mammalian brain occurred in the early 1960s, however, nearly 40 years passed before the scientific community generally recognized the existence of adult mammalian neurogenesis. Development of new technologies that facilitate the identification of newborn neurons in the early 1990s has been central to expanding our understanding of adult neurogenesis as a process influencing mammalian brain plasticity. Subsequently, the field of adult neurogenesis progressed tremendously thanks to continuous technical advances allowing in vivo and in vitro manipulations of adult neural progenitors. Today, a core understanding of various aspects of adult neurogenesis has emerged, including neural progenitor proliferation and fate-specification, and the migration, maturation, and synaptic integration of newborn neurons into functional circuits. However, numerous questions remain open. This research topic issue gather
