Summary
Sexually dimorphic behavior is influenced by olfactory cues. While sex-specific odor ligands are identified, the neural circuits driving gender-dimorphic responses are still under investigation.
Area of Science:
- Neuroscience
- Behavioral Biology
- Genetics
Background:
- Sexually dimorphic behavior arises from genetic and sensory factors.
- Olfactory cues, including sex-specific pheromones, play a crucial role in gender-dimorphic behavior.
- Advances in identifying olfactory ligands contrast with limited understanding of neural response mechanisms.
Purpose of the Study:
- To explore the neural mechanisms underlying gender-dimorphic responses to olfactory cues.
- To investigate the components of sexually dimorphic olfactory circuits.
Main Methods:
- Identification of sex-specific olfactory ligands.
- Investigation of neural circuits in model organisms like Drosophila and mice.
Main Results:
- Sex-specific odor compounds (pheromones) have been purified and isolated.
- Initial progress has been made in identifying components of sexually dimorphic olfactory circuits in Drosophila and mice.
Conclusions:
- Understanding the neural basis of olfactory-driven sex differences is crucial.
- Further research is needed to fully elucidate the neural mechanisms of gender-dimorphic olfactory responses.

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.

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.

01:20Mate Choice
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
