With this atlas in place, we mapped sex differences in the atlas and adult connectomes, identifying female-specific apoptosis and transcriptional divergence as drivers of sexually dimorphic development. 7/8

Late born neurons from each lineage form trajectories, with consecutively born neuron types arranged by birth order. By aligning 83 such trajectories, we directly compared how expression dynamics unfold across lineages. 5/8

With unprecedented 38× coverage, our atlas resolves single neuron clusters and shows that separate waves of neurogenesis use different modes of molecular identity encoding: discrete in early born and continuous in late born. 3/8
