Electroolfactogram (EOG) Recording in the Mouse Main Olfactory Epithelium.
Olfactory sensory neurons in the main olfactory epithelium (MOE) are responsible for detecting odorants and EOG recording is a reliable approach to analyze the peripheral olfactory function. However, recently we revealed that rodent MOE can also detect the air pressure caused by airflow. The sensation of airflow pressure and odorants may function in synergy to facilitate odorant perception duri...
متن کاملAnalyzing Responses of Mouse Olfactory Sensory Neurons Using the Air-phase Electroolfactogram Recording
Animals depend on olfaction for many critical behaviors, such as finding food sources, avoiding predators, and identifying conspecifics for mating and other social interactions. The electroolfactogram (EOG) recording is an informative, easy to conduct, and reliable method to assay olfactory function at the level of the olfactory epithelium. Since the 1956 description of the EOG by Ottoson in fr...
متن کاملOdorant receptor proteins in the mouse main olfactory epithelium and olfactory bulb
In the mouse, odorant receptor proteins (ORs) are G-protein-coupled receptors expressed in mature olfactory sensory neurons (OSNs) of the main olfactory epithelium (MOE). ORs mediate odorant reception at the level of the OSN cilia. Most of the ∼1100 OR genes in the mouse genome are expressed, at the RNA level, in mature OSNs. The literature on antibodies against ORs is limited, and most reports...
متن کاملAn electroolfactogram study of odor response patterns from the mouse olfactory epithelium with reference to receptor zones and odor sorptiveness.
Olfactory sensory neuron (OSN) responses to odors, measured at the population level, tend to be spatially heterogeneous in the vertebrates that have been studied. These response patterns vary between odors but are similar across subjects for a given stimulus. However, few species have been studied making functional interpretation of these patterns problematic. One proximate explanation for the ...
متن کاملA Sensor for Low Environmental Oxygen in the Mouse Main Olfactory Epithelium
Sensing the level of oxygen in the external and internal environments is essential for survival. Organisms have evolved multiple mechanisms to sense oxygen. No function in oxygen sensing has been attributed to any mammalian olfactory system. Here, we demonstrate that low environmental oxygen directly activates a subpopulation of sensory neurons in the mouse main olfactory epithelium. These neur...
