Summary
Vertebrate pheromone detection is complex, involving both the olfactory epithelium and vomeronasal organ. Multiple receptor families and distinct neural pathways contribute to sensing these crucial chemical signals.
Area of Science:
- Neuroscience
- Olfactory receptor research
- Chemical communication
Background:
- Traditionally, the olfactory epithelium (OE) detects odors, and the vomeronasal organ (VNO) detects pheromones.
- Recent studies indicate the OE also detects pheromones in vertebrates.
- Both OE and VNO express distinct pheromone receptor families.
Purpose of the Study:
- To explore the complex mechanisms of pheromone perception in vertebrates.
- To investigate the roles of different receptor families and neural pathways in pheromone detection.
- To highlight the species-specific differences in pheromone sensing systems.
Main Methods:
- Analysis of receptor gene expression in OE and VNO.
- Identification of novel pheromone receptors.
- Investigation of signal transduction pathways and neural circuitry.
Main Results:
- Rodent VNO expresses V1R and V2R receptors for pheromones.
- A trace amine-associated receptor (TAAR) in mouse OE detects putative pheromones.
- Distinct signaling pathways and neural circuits are utilized by different receptor families.
- Functional roles of these receptors vary across vertebrate species.
Conclusions:
- Vertebrate pheromone perception involves intricate interactions between OE and VNO.
- Multiple receptor families and signaling pathways contribute to pheromone detection.
- The complexity of pheromone sensing systems is greater than previously understood and shows species-specific variations.

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.

01:03Olfactory 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...
01:26Introduction to Special Senses
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive functions.
01:31What is a Sensory System?
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.
01:27Tactile and Chemical Senses
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex. This...
