During embryonic development the nervous system is confronted with a problem of enormous complexity; to progress from a thin sheet of neuroepithelial cells to a network of neuronal circuitry that is able to process sensory information and generate an appropriate motor output. One of the ways that the mammalian nervous system achieves this end point is by overproducing both neurons and neuronal connections, and then eliminating those cells and/or connections that are not appropriate. However, this is not something that is limited to the developing nervous system. Many of the same cellular mechanisms remain "in place" in adult animals, thereby allowing structural and/or functional remodeling in response to physiological stimuli, and providing repair mechanisms for the injured and traumatized mature nervous system.
These complex developmental processes are determined by an intimate interplay between intrinsic cellular programs and environmental cues. Within this broad context, my laboratory is interested in understanding how growth factors and neural activity regulate the genesis, survival and growth of developing neurons and regulate the establishment of appropriate neuronal connectivity
