We are excited to announce the publication of our insight paper, written to accompany the most recent publication from the Rubin Lab. This incredible paper uses the Split-GAL4 system to dissect the Drosophila central complex into cell-type specific driver lines and characterizes these based on neurotransmitter and neuropeptide expression, as well as identifying a role in sleep-related behavior. We are grateful to have been asked to write an eLife Insight article to help bring attention to this important work.
