  • Title: Newborn neurons in the adult olfactory bulb: unique properties for specific odor behavior.
    Author: Breton-Provencher V, Saghatelyan A.
    Journal: Behav Brain Res; 2012 Feb 14; 227(2):480-9. PubMed ID: 21843557.
    Abstract:
    The generation of new cells in the adult brain reveals a new form of plasticity in the neuronal network. New cells are constantly migrating to and integrating into the pre-existing neuronal network in the olfactory bulb. The exact role of new neurons in the adult olfactory bulb and in odor behavior remains elusive despite continuous progress. The unique properties of these adult-born interneurons that distinguish them from pre-existing bulbar neurons allow them to adapt the processing of odor information in the neuronal network of the olfactory bulb in response to sensory experience. The combination of diverse methods for modulating neurogenesis levels with distinct behavioral paradigms has revealed that interneurons generated during adulthood play a role in olfactory behavior. In this review we provide an overview of the unique properties of adult-born neurons that integrate into the olfactory bulb as well as their role in odor behavior.
