Abstract
Insect neurons are generated by the proliferation of progenitor cells called neuroblasts. In Drosophila melanogaster, the neuroblasts develop from a special region of the ectoderm, the neurogenic region (NR), or neuroectoderm; in this region neighboring cells have to decide between one of two alternative fates and develop either as neuroblasts or as epidermoblasts (progenitor cells of the epidermis). Due to its apparent simplicity, the decision of neuroectodermal cells for the neural or the epidermal fate is a good example to investigate the mechanisms of origin of cell diversity in a multicellular organism.
