Neural circuit basis of aversive odour processing in Drosophila from sensory input to descending output.

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.

Neurogenetic dissection of the Drosophila innate olfactory processing center

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.

An olfactogenetic approach identifies olfactory neurons and brain centers directing negative oviposition decisions in Drosophila.

This paper introduces olfactogenetics to specifically activate olfactory neurons in Drosophila and identifies neuron types and brain regions involved in suppressing oviposition.
