Although eusociality evolved independently within several orders of insects, research into
the molecular underpinnings of the transition towards social complexity has been confined …

The human nose is often considered something of a luxury, but in the rest of the animal
world, from bacteria to mammals, detecting chemicals in the environment has been critical to …

Genetic intervention in the fly Drosophila melanogaster has provided strong evidence that
the mushroom bodies of the insect brain act as the seat of a memory trace for odours. This …

Fruit flies are attracted by a diversity of odors that signal the presence of food, potential
mates, or attractive egg-laying sites. Most Drosophila olfactory neurons express two types of …

We provide a systematic analysis of how odor quality, quantity, and duration are encoded by
the odorant receptor repertoire of the Drosophila antenna. We test the receptors with a panel …

To sense myriad environmental odors, animals have evolved multiple, large families of
divergent olfactory receptors. How and why distinct receptor repertoires and their associated …

Internal physiological states influence behavioral decisions. We have investigated the
underlying cellular and molecular mechanisms at the first olfactory synapse for starvation …

Drosophila olfactory sensory neurons (OSNs) each express two odorant receptors (ORs): a
divergent member of the OR family and the highly conserved, broadly expressed receptor …

Summary Background: Olfactory receptor neurons (ORNs) convey chemical information into
the brain, producing internal representations of odors detected in the periphery. A …

The insect chemoreceptor superfamily in Drosophila melanogaster is predicted to consist of
62 odorant receptor (Or) and 68 gustatory receptor (Gr) proteins, encoded by families of 60 …
