Odor-evoked inhibition in primary olfactory receptor neurons
Chemical Senses, 1994Odors 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, 2000Abstract 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
1988The 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
1992Olfactory 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
1994Approximately 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.

Mechanisms of Afterhyperpolarization in Lobster Olfactory Receptor Neurons
Journal of Neurophysiology, 1998Corotto, Frank S. and William C. Michel. Mechanisms of afterhyperpolarization in lobster olfactory receptor neurons. J. Neurophysiol. 80: 1268–1276, 1998. In lobster olfactory receptor neurons (ORNs), depolarizing responses to odorants and current injection are accompanied by the development of an afterhyperpolarization (AHP) that likely contributes to

Ionotropic GABA Receptor From Lobster Olfactory Projection Neurons
Journal of Neurophysiology, 1997Zhainazarov, A. B., M. Wachowiak, A. Boettcher, S. Elenes, and B. W. Ache. Ionotropic GABA receptor from lobster olfactory projection neurons. J. Neurophysiol. 77: 2235–2251, 1997. This study reports an ionotropic GABA (γ-aminobutyric acid) receptor in projection neurons acutely dissociated from the olfactory lobe of the brain of the spiny lobster and ...

Excitable properties of olfactory receptor neurons.
The Journal of neuroscience : the official journal of the Society for Neuroscience, 1987Action potential-generating properties of olfactory receptor neurons in the olfactory epithelium of the salamander, Ambystoma tigrinum, were studied in control animals, and 2 and 4 weeks after olfactory nerve transection. The threshold for impulse generation in response to injected current was extremely low (74 +/- 46 pA).
