Neurogenesis in the Developing and Adult Mammalian Brain
Brain size and function depend on the generation of the appropriate number of neurons during development and their proper assembly into neural circuits. Our lab is dedicated to the study of neurogenesis (i.e., the generation of new neurons) in the mammalian forebrain. Specifically, we want to know how neurogenesis is controlled during development and why it persists in only a few particular brain regions in adulthood. To address these issues, we are applying molecular, cellular and anatomical techniques to a variety of mammalian models. Knowing the mechanisms that govern neurogenesis can further our understanding of the developmental basis of both the generation of neural diversity across species as well as the pathogenesis of abnormalities in humans. Moreover, continued neuronal production may have implications for plasticity in the adult brain – particularly for enhancing the brain's own capacity for self-repair after neuronal loss due to injury or neurodegenerative disease.
