Geosmin avoidance in Drosophila runs from a labelled line at the periphery into a distributed central representation spanning 80 third-order cell types, then into specific descending neurons.

BAcTrace is a new genetically encoded tool for retrograde neuronal tracing validated in Drosophila olfactory circuits.

The paper identifies 165 cell types in the Drosophila lateral horn and shows that 33 of them have stereotyped odor responses, revealing principles of odor categorization in a higher olfactory center.

The paper identifies two LH cell-types in Drosophila that are required for aversive memory retrieval and show that memory information is passed from the mushroom body to the lateral horn.

The paper generates split-GAL4 driver lines to map and functionally characterize 82 cell types in the Drosophila lateral horn, revealing connectivity with mushroom bodies and identifying cell types that influence behavior.

This paper introduces a chemical tagging method for rapid, low-background labeling of thick tissues, demonstrating 100x faster staining of whole-mount fly brains.
