How does the nervous system develop? This problem has intrigued embryologists for more than a century. In fact, early investigators formulated many of the fundamental questions about how the nervous system arises, how neurons acquire their identities, and how neuronal processes find and form synapses with appropriate target cells. To answer these questions, it would be ideal to have a single species with which cellular, molecular, and genetic analyses could be carried out on individually identified neurons and their associated cells as they develop and generate a complex nervous system. The zebrafish (Brachydunio rerio) has the potential to be such a species. In this essay, I will discuss aspects of the zebrafish that make its embryo an excellent material for developmental studies, results that have extended our knowledge of nervous system development, and future prospects for this work.
