The Drosophila adult brain: short overview of structure, function, and resources Graphical Review Paper.

This short review is targeted at researchers new to the Drosophila model (thereafter: a Drosophilist) in the field of neuroscience. We aim to provide an introductory overview of our current understanding of the adult (thereafter: Drosophila) brain, its structures, circuitry, and associated behaviours, as well as links to additional resources for more in-depth information. Throughout this overview, we mostly provide references to seminal review articles instead of the original research articles that are thoroughly provided within each review. We do not claim to present an exhaustive exploration of this rapidly expanding field, or of its history. Rather, the field currently lacks a short and simple up-to-date guide to the adult Drosophila brain. Finally, even though connectomes for the full larval brain and the adult ventral nerve cord have recently been made available, we are restricting our focus to the adult brain.
