  • Development of the vertebrate visual system,
  • Cellular and molecular basis of learning and memory

The goal of my research is to understand how experience differentially influences the juvenile versus adult mammalian brain.  A primary focus is the role of experience in the regulation of the visual system.  Pioneering work in the mammalian visual system demonstrated a significant decline in experience-dependent synaptic plasticity over the course of postnatal development. One of the severe consequences of the loss of experience-dependent synaptic plasticity is the inability to recover from form-deprivation amblyopia (Amblyopia ex anopsia) caused a unilateral congenital cataract.  If untreated, neurons in the binocular cortex become dominated by the unaffected eye, and resistant to recovery by removal of the cataract.  Recently we have developed a method (binocular visual deprivation through dark exposure) that allows for the recovery from severe amblyopia in rodents, even when a monocular occlusion is initiated immediately at eye opening and continues until adulthood.  This work was recognized with the 2010 Advancement of Science Award by the Neuro-Optometric Rehabilitation Association.  Currently, we are using a multidisciplinary analysis that includes electrophysiology, molecular biology, biochemistry, and behavior to characterize the functional consequences, and the molecular mechanisms, by which dark exposure promotes the recovery from chronic deprivation amblyopia.
