Brain Region List by Strausfeld/Otsuna

The following list consolidates the brain regions described on the website Flybrain, and in Otsuna and Ito (2006, J. Comp. Neurol. 497:928-958). Contents of the Flybrain website are based on definitions in "Atlas of an Insect Brain" (Strausfeld, N. J., 1976, Springer-Verlag (Berlin, New York)).
Click each brain region names for detailed descriptions, or relationship to the newer brain region nomenclature system.
Names with asterisks (*) are those defined or referred only by Otsuna and Ito.
