Abstract
Our understanding of the molecular and cellular organization
of the Drosophila melanogaster olfactory system has increased
dramatically in recent years. A large family of \~60 odorant
receptors has been identified, and many of these receptors
have been functionally characterized. The odor responses of
olfactory receptor neurons have been characterized, and much
has been learned about how odors are represented in olfactory
centers in the brain. The circuitry of the olfactory system
has been studied in detail, and the developmental mechanisms
that specify the wiring and functional diversity of olfactory
neurons are becoming increasingly well understood. Thus,
functional, anatomical and developmental studies are rapidly
being integrated to form a unified picture of odor coding in
this model olfactory system.
