1077-The Drosophila Central Brain Neuron Atlas

The paper detail the creation of a comprehensive single-cell transcriptomic atlas of the adult Drosophila central brain, encompassing over 329,000 neurons. By integrating multiple datasets, researchers achieved high-resolution coverage that identifies more than 4,000 distinct neuronal subtypes. This study reveals that a neuron's adult identity is primarily dictated by its developmental origin, specifically its lineage and birth order. The atlas utilizes a combinatorial genetic code of transcription factors to map these cells to their precise anatomical and functional locations. Furthermore, the data highlights how temporal developmental programs remain visible in maturity, distinguishing early-born from late-born neurons through specific gene expression. This resource serves as a vital bridge between neurodevelopmental processes and the complex neural circuits that drive adult behavior.References:Allen A M, Neville M C, Nojima T, et al.
