Temporal Resolution in Olfaction: Stimulus Integration Time of Lobster Chemoreceptor Cells

Journal of Experimental Biology, 1996
ABSTRACT The stimulus integration time of lobster olfactory receptor cells in situ was determined using extracellularly recorded spiking responses from receptor cells and on-line high-resolution measurement of odor square pulses. At a fixed odor concentration, odor steps of 200 ms duration elicited maximum responses; shorter odor steps ...

Characterization of nicotinic acetylcholine receptors in cultured arterial chemoreceptor cells of the cat

Brain Research, 2003
Neurotransmitters appear to be involved in chemotransmission of the carotid body, a major arterial chemoreceptor. Substantial data indicate that acetylcholine (ACh) is an excitatory neurotransmitter in the carotid body, regulating the excitability of afferent nerve endings and glomus cells (putative chemoreceptor cells).

Distribution of epithelioid cells in the wall of the chicken aorta and their functional role as chemoreceptors

The Anatomical Record, 1995
AbstractBackground: The ultrastructural characteristics of epithelioid cells in the wall of the chicken aorta have been studied by several investigators. Their characteristics were homologous to those of carotid body type I cells and are considered to be one of the peripheral chemoreceptors.

Distribution of chemoreceptors to quinine on the cell surface of Paramecium caudatum

Journal of Comparative Physiology A, 1996
The topological distribution of the chemoreceptors to quinine in the membrane of a ciliate Paramecium caudatum were examined by conventional electrophysiological techniques. A CNR-mutant specimen defective in voltage-gated Ca channels produced a transient depolarization followed by a transient hyperpolarization and a sustained depolarization when 1 mM ...

Responses of the chemoreceptors of the cat carotid body perfused with cell-free solutions

Irish Journal of Medical Science, 1979
The responsiveness of chemosensory discharge recorded from the carotid sinus nerve to chemoreceptor stimulation underwent a progressive attenuation during perfusion of the vascularly isolated carotid body with physiological saline solutions. These attenuations mirrored the reductions of the oxygen usage of the carotid body measured under identical ...
