Research

Central nervous system (CNS) injuries affect multiple cell types and after the initial damage, additional tissue loss exacerbates the injury leading to permanent dysfunction. There is no effective cure for CNS injuries often leading to a lifetime of therapy and permanent disability. The Mruk Lab studies CNS injuries using the zebrafish because although the zebrafish CNS shares many organizational, cellular and molecular pathways with mammals, functional recovery occurs after injury. We use a combination of electrophysiology, fluorescent imaging, behavior, and bioinformatics to understand how the entire CNS network responds and subsequently recovers from injury.
