| Description: | Dr. Wong studies the development of neural circuits. Her lab applies a multidisciplinary approach to investigate how retinal circuits in zebra fish and mice are assembled appropriately during development. She uses in vivo and in vitro imaging approaches to determine how the unique axonal and dendritic morphologies of all classes of retinal neurons are established during development. She uses transgenic animals lacking specific forms of neurotransmission to examine the role of cell-cell interactions in specifying neuronal structure and connectivity. She also combines imaging methods with electrophysiology approaches to determine how functional circuits are established, and to relate structural changes to neuronal processing.
