title: Neuronal specification.
abstract: Cell fate specification, a central problem in developmental biology, presents an intriguing challenge in the studies of neural development. How are certain cells in the embryonic ectoderm selected to be neuronal precursors? How do individual neuronal precursors and their progeny cells acquire their own identity? These are just some of the questions that recent developments have begun to elucidate.
