Analyzing the variation in different subpopulations of newborn neurons is central to the study of adult hippocampal neurogenesis. The acclaimed working hypothesis that different subpopulations of newborn, differentiating neurons could be playing different roles arouses great interest. Therefore, the physiological and quantitative analysis of neuronal subpopulations at different ages is critical to studies of neurogenesis. Such approaches allow cells of different ages to be identified by labeling them according to their probable date of birth. Until very recently, only neurons born at one specific time point could be identified in each experimental animal. However the introduction of different immunohistochemically compatible markers now enables multiple subpopulations of newborn neurons to be analyzed in the same animal as in a line-up, revealing the relationships between these subpopulations in response to specific influences or conditions. This review summarizes the current research carried out using these techniques and outlines some of the key applications. The accurate labeling of newborn cells in the adult brain poses a fundamental challenge in the study of adult neurogenesis. Adult brain neurogenesis is closely linked with learning and memory, and it has also been implicated in anxiety and depression for recent reviews, see Aimone et al. Adult neurogenesis has attracted considerable attention due to the cellular properties observed during this period, which may be adapted to rescue neuronal loss due to aging or neurodegenerative processes.

Birth dating of cells is important to fully elucidate when a cell has been created, to determine what factors or conditions may have led to its conception. Birth dating has been applied within many cell constructs, though recent attention has focused on cells within the central nervous system. With the relatively recent discovery of neuro-genesis, a process of creating functionally integrated neurons from progenitor cells, a plethora of innovative techniques to track the rate of cell birth have been developed.

Neurochemical phenotype and birthdating of specific cell populations in the chick retina. Karin da Costa calaza I ; Patricia F. Gardino II. Correspondence to. The chick embryo is one of the most traditional models in developing neuroscience and its visual system has been one of the most exhaustively studied. The retina has been used as a model for studying the development of the nervous system. Here, we describe the morphological features that characterize each stage of the retina development and studies of the neurogenesis period of some specific neurochemical subpopulations of retinal cells by using a combination of immunohistochemistry and autoradiography of tritiated-thymidine. It could be concluded that the proliferation period of dopaminergic, GABAergic, cholinoceptive and GABAceptive cells does not follow a common rule of the neurogenesis. In addition, some specific neurochemical cell groups can have a restrict proliferation period when compared to the total cell population. Key words:
