In this paper we identify what should be the majority (but not quite all – see doublesex) of the anatomical differences between male and female fly brains both at the level of gross anatomy and clusters of a 20 or so neurons derived from specific neuroblasts. As a puzzle see if you can identify some of the neuropil differences between male and female brains that are visible in these two images:
