The organization of olfactory projection neurons and their synaptic connectivity with third-order neurons studied along with olfactory responses suggest that the labeled-line design is partially at work in the Drosophila olfactory system.

Experiments and modeling suggest that a mechanism involving positive and negative feedback can explain the relationship between the neural activity of socially interacting bats.

Analysis of neuronal circuit architecture provides mechanistic insights into what an adult fly can learn, remember, and use to guide its behavior.
