Opposing intrinsic temporal gradients guide neural stem cell production of varied neuronal fates

Abstract

Changes over time build neuronal diversity Although neural progenitors can keep generating new neurons, they can generate different neurons as the organism develops. Two different sections of the Drosophila brain, the mushroom bodies and the antennal lobes, show this characteristic, although the antennal lobes produce more different types of neurons over development than do the mushroom bodies. Liu et al. identified two RNA-binding proteins that manage this change over development in both settings. Science , this issue p. 317
