During ~5 days of Drosophila neurogenesis (late embryogenesis to the beginning of pupation), a limited number of neural stem cells produce ~200,000 neurons comprising hundreds of cell types. To build a functional nervous system, neuronal types need to be produced in the proper place, appropriate number, and correct time. We discuss how neural stem cells (neuroblasts) obtain “area codes” for their positions in the nervous system (spatial patterning) and how they keep time to sequentially produce neurons with unique fates (temporal patterning). We focus on specific examples that demonstrate how a relatively simple patterning system (Notch) can be used reiteratively to generate different neuronal types. We also speculate how different modes of temporal patterning operating over short time periods versus long time periods might be linked. We end by discussing how specification programs are integrated and lead to the terminal features of different neuronal types.
