Biologists Uncover How Fruit Flies Track Smell Ribbons in Air
Neuroscientists discover how fruit flies use precise working memory and directional velocity sensors to navigate chaotic airborne odor plumes.
A breakthrough neurobiology study published by researchers at Johns Hopkins reveals the complex neural architecture that enables fruit flies to pinpoint scent sources across turbulent wind currents using a combination of working memory and wind-vector sensing.
Because wind disperses odor molecules into fragmented, invisible filaments rather than smooth gradients, flies must rapidly store the timestamp of scent contacts and re-orient their flight heading based on ambient air velocity.
