Physiology of Smell and Olfactory Pathway

Physiology 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.
The olfactory...

Olfaction

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.
The olfactory receptors are embedded in the cilia of the...

Background:

Male moths navigate towards females using pheromones, a process relevant to decision-making models.
The exploration-exploitation (EE) model describes balancing searching for new resources versus utilizing known ones.

Purpose of the Study:

To apply the EE model to understand male moth pheromone-driven flight paths.
To investigate how airflow fluctuations affect moth navigation strategies.

Main Methods:

Utilized wind tunnel experiments with 3D infrared tracking of male moth flight.
Introduced controlled airflow disturbances to analyze flight responses.
Employed a genetic algorithm to separate exploration and exploitation phases in flight trajectories.

Main Results:

Demonstrated an increasing exploration-to-exploitation rate (EER) with greater distance from the pheromone source.
Revealed a correlation between higher EER and increased airflow fluctuations near the source.
Explained enhanced EER in turbulent conditions using olfactory navigation simulations and a moth-inspired model.

Conclusions:

Male moth navigation aligns with the EE model, adapting search intensity to environmental conditions.
Increased turbulence enhances the exploration-to-exploitation rate in male moths.
Findings contribute to understanding biological navigation and developing bioinspired algorithms.
