2 Views Inside the Brain of a Fruit Fly (IMAGE) Max Planck Institute for Chemical Ecology Caption This shows two views inside the brain of a fruit fly while it is smelling; left: active glomeruli (represented by bright colors) after stimulation with a deterrent odor (linalool); right: active glomeruli after application of an attractant (3-methylthio-1-propanol). This shows that deterrent responses are generated in lateral areas of the brain, whereas attractant responses are generated in medial areas.
