1/8 Breathing seems automatic. But it's a finely tuned motor behavior that has to be controlled. In this preprint, I map the circuits that match a fly's respiration to the metabolic demands of flight and mitigate the risk of dehydration. 🧵🪰 www.biorxiv.org/content/10.6...

Some fly neurons are “dimorphic”, existing in both males and females but connecting to different neighboring neurons. Neighbors may be “isomorphic”, the same in both male and female; or sex specific; or dimorphic themselves. Here's an example, the type AOTU012, present in left and right instances.

"The layoffs jeopardize this resource, which has served more than 4,000 labs for about three decades." 4000 labs is a severe understatement, likely off by an order of magnitude. Even non-fly people use and benefit from FlyBase. It is one of the cornerstones of the genome era.
