title: Out-foxing fate; molecular switches create neuronal diversity in the retina.
abstract: Progenitor cells in the mammalian retina generate at least 55 distinct kinds of neurons. Two reports in this issue of Neuron reveal two transcription factors (Foxn4 and Bhlhb4) that contribute to the development of this remarkable cellular diversity.
