My lab takes an integrative approach to studying the development of specific neuronal connections in the vertebrate central nervous system. We focus our research efforts on how patterns of neuronal activity and of molecular cues that occur during development cause the precise connectivity between neurons that is found in the adult brain. We use a number of different anatomical and physiological techniques to answer this basic developmental question. We hope that this inquiry-driven approach will provide data useful for formulating generalized rules of development in the nervous system. Our studies of the ferret visual system focus on the question of how the functional architecture of the lateral geniculate nucleus and the visual cortex develop. We use pharmacological and molecular methods to alter patterns of neuronal activity and molecular cues in the developing visual system, and use single-unit electrophysiological recordings, optical imaging of intrinsic signals and neuroanatomical tracing methods to assess the physiological and anatomical changes that occur during normal and abnormal development.
