Divisive Normalization in Olfactory Population Codes
TL;DR: This work exploits the orderly anatomy of the Drosophila antennal lobe to independently manipulate feedforward and lateral input to second-order projection neurons (PNs) and shows that discrimination by a linear decoder is facilitated by two complementary transformations: the saturating transformation intrinsic to each processing channel boosts weak signals, while normalization helps equalize responses to different stimuli.

Sensory processing in the Drosophila antennal lobe increases reliability and separability of ensemble odor representations.
TL;DR: Several fundamental principles of olfactory processing in the Drosophila melanogaster antennal lobe are described, through the systematic analysis of input and output spike trains of seven identified glomeruli, and it is shown that a linear discriminator classifies odors more accurately using PN spike trains than using an equivalent number of ORN Spike trains.

Elementary Response of Olfactory Receptor Neurons to Odorants
TL;DR: It is reported that the elementary response in olfactory transduction is extremely small, which appears fundamentally different from that of phototransduction.
Organization of descending neurons in Drosophila melanogaster.

TL;DR: The distribution ofDNs in Drosophila is compared to those reported previously in other insects and it is concluded that the organization of DNs in insects is highly conserved.
Signaling by olfactory receptor neurons near threshold
TL;DR: The signaling threshold of the olfactory receptor neuron (ORN) is reported here and it takes about 35 odorant-binding events successfully triggering transduction during a brief odorant pulse in order for an ORN to signal to the brain.
