Brain Wiring Gone Awry: Investigating the Cellular Basis of Neurological Disorders

Jennifer Round, Ph.D.
Assistant Professor of Biology and Neuroscience
Ursinus College

Advances in genomics have allowed us to link specific genes to many common neurodevelopmental disorders, but the cellular defects that lead to these conditions are still poorly understood. My lab investigates a gene family that has been linked to multiple brain disorders, including Tourette syndrome and schizophrenia. We use zebrafish as a convenient model to explore the roles of these genes in neuron growth, synapse formation, and cell survival during development. As we gain new knowledge of the basic biology of nervous system wiring, we can enhance our understanding of the cellular basis of neurological disease.
