Abstract

In this review we summarize studies of adult neurogenesis, from original descriptive accounts to more recent work aimed at identifying factors that influence neurogenesis as well as its possible function. Much of the recent work has focused on the relationship between neurogenesis and learning: we therefore present critical analyses of specific experiments and the conclusions that can be drawn from them. We describe two avian models, song learning and food caching, and argue that because these models have a high degreeof ethological validity they are particularly well-suited for investigating the fate and specific functions of adult-born neurons. We also describe work on neurogenesis in juveniles and how that has contributed to our understanding of the relationship between neurogenesis and learning, but caution against drawing inferences regarding the function of adult neurogenesis from these studies in juveniles because the cellular and functional mechanismsunderlying juvenile and adult neurogenesis; are likely distinct. We critically review several experiments investigating mammalian postnatal neurogenesis, and describe how particular flaws in the assumptions underlying their experimental design may render some of their results misleading. We suggestthat by increasing the ethological validity of the mammalian models, it may be possible to strengthen the conclusions that can be drawn from such investigations. We conclude that there is inadequate empirical evidence linking either the phenomenon of adult neurogenesis with a specific role in learning, or learning-associated paradigms with an increase in or enhancement ofadult neurogenesis, and indeed, substantial evidence counter to these hypotheses.
