A global molecular code for birth order and neuronal identity in Drosophila

TL;DR - A high-resolution developmental transcriptional atlas of the Drosophila nerve cord reveals a shared molecular code linking neuronal birth order to cell identity. This provides a framework for understanding how developmental timing organizes neuronal diversity.

• Maps transcriptional states during Drosophila nerve-cord development at high resolution.
• Identifies a shared transcriptional signature that records when neurons are born.
• Connects birth-order information with the organization of diverse neuronal identities.
