ABSTRACT

During the last decade neuroscientists have shown an increasing interest in adult neurogenesis and a number of studies have been focused on the role that it could play in learning and memory processes. Objective: the present work reviews the last evidences related to the possible role of adult neurogenesis in the hippocampus for learning and memory mechanisms. Development: one of the brain structures that generates new neurons during adulthood is the dentate gyrus of the Hippocampus. This structure is involved in learning and memory processes, and a plausible role for these newly born cells at the information processing level has been suggested. Conclusions: actual evidences do not provide a clear picture on the type of cognitive processes supported by adult-born neurons. Thus, different results have been found depending on the specific experimental and behavioural procedures used. Therefore, future research should consider how different tasks and experimental protocols affect to adult hippocampal neurogenesis in relationship to learning and memory mechanisms.
