Functional synapse formation between rat olfactory receptor neurons and olfactory bulb neurons in vitro

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 ...

Zinc nanoparticles interact with olfactory receptor neurons

BioMetals, 2010
Zinc metal nanoparticles strongly enhance odorant responses of olfactory receptor neurons. Olfactory receptors belong to the large superfamily of G-protein coupled receptors. A theoretical model based on experimental results explains a stoichiometry of metal nanoparticles receptor interaction. The model is similar to that used by A.V.

Primary Culture of Adult Mouse Olfactory Receptor Neurons

Experimental Neurology, 1998
Olfactory 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, 1994
To 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, 1991
The 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.

Odor-evoked inhibition in primary olfactory receptor neurons

Chemical Senses, 1994
Odors can inhibit as well as excite lobster olfactory receptor cells. Inhibitory components of an odor mixture act within the normal, first 500 ms odor sampling interval of the animal to reduce the peak magnitude and increase the latency of the net excitatory receptor potential in a concentration-dependent manner.

Biosensing by insect olfactory receptor neurons

Sensors and Actuators B: Chemical, 2000
Abstract Action potentials of insect olfactory receptor neurons (ORN) were picked up with microelectrodes and amplified by a high-impedance amplifier connected to an oscilloscope, an audio amplifier, and an instrumentation amplifier. The amplified action potentials and odour exposure times were recorded on a DAT (digital audio tape) recorder for ...

Axoplasmic Transport in Olfactory Receptor Neurons

1988
The function of a cell can only be fully understood through the knowledge of the internal machinery acting both in preserving the cell’s shape and biochemical integrity and in maintaining the specific requirements of any highly specialized cell. Because nerve cells are made to convey information over long distances along their axons, knowledge of the ...

Biophysical Properties of Olfactory Receptor Neurones

1992
Olfactory receptor neurones are astonishingly similar in all species from snails to man. The cell is divided into four compartments: the cilia being the interface to the environment, the dendrite which couples the cilia to the cell’s soma, the soma, and the initial segment of the axon.

Integration of Olfactory Input by Lobster Olfactory Receptor Neurons

1994
Approximately 50% of lobster olfactory receptor neurons (ORNs) support both odor-evoked excitatory and inhibitory conductances. In the present study we show that inhibition rapidly and reversibly diminishes both the intensity and the time course of the output of lobster ORNs within the natural sampling interval.
