Amphibian olfactory receptor neurons express olfactory marker protein
Brain Research, 1992Expression of olfactory marker protein (OMP) in olfactory receptor neurons (ORNs) in two amphibians was investigated by immunohistochemical methods. The OMP immunoreactivity was observed in the cilia, apical dendritic knobs, dendrites and somas of ORNs; the axons of ORNs also showed intense immunoreactivity for OMP throughout their course from the ...

Impulse conduction of olfactory receptor neuron axons
Microscopy Research and Technique, 2002AbstractCompound action potentials were recorded from rat olfactory receptor neuron axons at measured distances from the stimulation electrode along the lateral surface of the main olfactory bulb. Distances were plotted as a function of the latencies measured from stimulus onset to the prominent negative trough of the triphasic compound action ...

Inward rectification in rat olfactory receptor neurons
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1991Inwardly rectifying currents in enzymically dissociated olfactory receptor neurons of rat were studied by using patch-clamp techniques. Upon hyperpolarization to membrane potentials more negative than -100 mV, small inward-current relaxations were observed.

Calcium-signaling networks in olfactory receptor neurons
Neuroscience, 2008The olfactory neuroepithelium represents a unique interface between the brain and the external environment. Olfactory function comprises a distinct set of molecular tasks: sensory signal transduction, cytoprotection and adult neurogenesis. A multitude of biochemical studies has revealed the central role of Ca(2+) signaling in the function of olfactory ...

Mature olfactory receptor neurons express connexin 43
The Journal of Comparative Neurology, 2000The expression of the gap junction subunit connexin 43 was studied in the olfactory epithelium of adult mice. In agreement with conclusions from previous immunohistochemical studies, we observed expression of mRNA encoding for connexin 43 in layers of the epithelium containing nuclei belonging to sustentacular cells.

Preparation of isolated mouse olfactory receptor neurons
Pflügers Archiv - European Journal of Physiology, 1987A method is described for producing large numbers of isolated olfactory receptor neurons from adult mouse nasal epithelium. The dissociated neurons and other cell types isolated from nasal epithelium retain their morphology and can be identified visually.

Neuroscience Letters, 2000
To explore the mechanism of the synapse formation between olfactory receptor neurons and neurons in the olfactory bulb, blocks of olfactory epithelium and slices of olfactory bulb were cocultured by a modified slice culture method. After 4 days in culture, neuron specific fibers from the olfactory epithelium block extending to the olfactory bulb slice ...

Primary Culture of Adult Mouse Olfactory Receptor Neurons
Experimental Neurology, 1998Olfactory receptor neurons (ORNs) are unique because they can be replaced by stem cells throughout life. Previous studies have demonstrated that adult mouse olfactory epithelium (OE) injured by exposure to ZnSO4 through nasal irrigation can stimulate stem cell mitotic activity in situ, which continues when placed in culture.

Odor discrimination in single turtle olfactory receptor neuron
Neuroscience Letters, 1994To explore the ability of odor discrimination of olfactory receptor neurons, current responses to odorant cocktails were recorded from an isolated olfactory neuron of the turtle. Twenty-five percent of the neurons tested responded to both cAMP-dependent and the IP3-dependent odorant cocktails.

The second messenger cascade in olfactory receptor neurons
Current Opinion in Neurobiology, 1991The molecular cloning of components involved in the cAMP second messenger cascade has allowed their biochemical characterization and revealed properties that are important for their role in sensory transduction. Recent evidence suggests inositol 1,4,5-trisphosphate functions as an additional second messenger in olfactory signalling.
