The olfactory pathway in Drosophila.

Olfactory sensory neurons (red) provide olfactory input to the glomeruli of the antennal lobe (AL), where information is processed by local neurons before being transferred by projection neurons (blue) to the mushroom body (MB) and the lateral horn (LH). Frechter et al. combined whole-cell electrophysiology and anatomy to characterize the many different types of neurons in the LH. Dolan et al. used a range of tools to explore these neurons further. The image shows a so-called split-GAL4 line labeling a specific type of LH output neuron. Together, the two papers show that, rather surprisingly, the LH in Drosophila contains more neuron types than have been reported for higher brain regions in mammals.
