Summary
Fruit flies use their antennae and maxillary palps to detect odors, a process crucial for their behaviors. This research details the molecular and neural basis of the fruit fly olfactory system.
Area of Science:
- Neuroscience
- Sensory Biology
- Entomology
Background:
- The fruit fly (Drosophila melanogaster) displays complex odor-evoked behaviors.
- Understanding olfactory perception is key to sensory neuroscience.
Purpose of the Study:
- To review the molecular biology, neuroanatomy, and function of the peripheral olfactory system in Drosophila.
- To detail how olfactory sensory neurons (OSNs) and odorant receptors (ORs) contribute to odor perception.
Main Methods:
- Genomic and molecular neurobiology techniques.
- In vivo electrophysiology to decode ligand response profiles.
- Elucidation of axonal projections of OSNs.
Main Results:
- Drosophila possesses approximately 1200 OSNs on the antenna and 120 on the maxillary palps.
- A unique family of seven transmembrane domain odorant receptors (ORs) determines OSN odor specificity.
- The study provides insights into the initial logic of olfactory coding.
Conclusions:
- Advances in genomics and neurobiology offer detailed insights into the Drosophila olfactory system.
- The peripheral olfactory system's organization and function are well-characterized.
- This review synthesizes current knowledge on Drosophila olfaction.

01:25Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:03Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
01:20Physiology of Smell and Olfactory Pathway
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
