Our research is focused on the development and evolution of the mammalian neocortex. In our laboratory, we investigate the mechanisms involved in the development of the neocortex, specifically the establishment of discrete neocortical areas and the 'wiring' of the brain. We use a molecular, genetic approach to study neocortical development and regionalization, coupled with a neuroanatomical approach. We study specific genetic interactions to better understand the development of areas and topographies within the cortex. To do this, we use different mouse lines that are lacking genes important for the generation of cortical areas. Another area of interest involves the study of activity-related mechanisms. We am interested in how input-induced neocortical plasticity interacts with gene expression in the cortex. For example, does neocortical gene expression regulate cortical plasticity, or do alterations in input regulate patterns of gene expression, or both? Using state of the art molecular techniques, including in situ hybridization and in vitro electroporation, as well as immuno-histochemical, electrophysiological and tract tracing techniques, we hope to better understand the genetic (intrinsic) mechanisms as well as the epigenetic (extrinsic) activity-related mechanisms involved in the generation and maintenance of the very complex cerebral cortex.
