Dr. LaMantia is the Director of the GW Institute for Neuroscience.


Dr. LaMantia's laboratory explores genetic and molecular mechanisms of early forebrain development. We study signaling and transcriptional regulation of forebrain stem cell identity and the role of forebrain developmental regulatory genes in behavioral and psychiatric diseases including schizophrenia and autism. Our work is increasingly focused on how these mechanisms influence the development of neural circuits that process information in the cerebral cortex. These circuits are thought to be the target for developmental pathogenesis that leads to a variety of disorders of cortical circuitry including autism and schizophrenia. In addition, we have an ongoing research interest in molecular mechanisms that specify neural stem cells in the embryonic as well as adult nervous system. Our work on this problem focuses on the specification of the neural stem cell in the olfactory epithelium—the sensory receptor surface in the nasal cavity that mediates the sense of smell. This class of neural stem cells is established in the embryo during mid-gestation, and their progeny are retained in the adult olfactory epithelium throughout life to facilitate ongoing replacement of olfactory sensory receptor neurons that connect directly to the forebrain. The mechanisms that maintain this stem cell provide a superb model for considering neuronal regeneration as well as degenerative disorders including Alzheimer’s and Parkinson’s Disease that disrupt the ongoing replacement of olfactory sensory neurons.
