The Fly in the Room

Flies have poppy-seed sized brains, yet with our, by comparison, massive brains we often struggle to outwit them to our chagrin. Throughout our lives, all of us will have a considerable amount of experience with flies, mostly irritating ones, yet only a few of us make the effort to fully understand what their little brains are up to.

"They’re expert navigators, for one, zipping around without crashing into walls. They have great memories too, he adds.".....'“Fruit flies are very skillful,” he appraises. And all that skill, although contained in a brain the size of a poppy seed, involves some neural circuitry similar to our own, a product of our distant common ancestor. That’s why, as director of Janelia Research Campus, part of the Howard Hughes Medical Institute, he’s spent the last 12 years leading a team that’s mapping out the fly brain’s physical wiring, down to the very last neuron."'
