title: Born to run: patterning the Drosophila olfactory system.
abstract: The distributed, apparently random pattern of odorant receptor expression is thought to reflect a stochastic choice process. In this issue of Developmental Cell, Song et al. (2012) suggest that the Drosophila pattern is established secondarily from regionally specified cell populations through changes in transcription factor expression and cell migration.
