Effects of odor stimulation on antidromic spikes in olfactory sensory neurons.
Spikes were evoked in rat olfactory sensory neuron (OSN) populations by electrical stimulation of the olfactory bulb nerve layer in pentobarbital anesthetized rats. The latencies and recording positions for these compound spikes showed that they originated in olfactory epithelium. Dual simultaneous recordings indicated conduction velocities in the C-fiber range, around 0.5 m/s. These spikes are...

متن کاملEffects of cGMP and sodium nitroprusside on odor responses in turtle olfactory sensory neurons.
The effects of cGMP and sodium nitroprusside (SNP) on odor responses in isolated turtle olfactory neurons were examined. The inward current induced by dialysis of a mixture of 1 mM cAMP and 1 mM cGMP was similar to that induced by dialysis of 1 mM cAMP or 1 mM cGMP alone. After the neurons were desensitized by the application of 1 mM cGMP, 3 mM 8-(4-chlorophenylthio)-cAMP, a membrane-permeable ...
متن کاملOdor-induced cAMP production in Drosophila melanogaster olfactory sensory neurons.
Insect odorant receptors are seven transmembrane domain proteins that form cation channels, whose functional properties such as receptor sensitivity are subject to regulation by intracellular signaling cascades. Here, we used the cAMP fluorescent indicator Epac1-camps to investigate the occurrence of odor-induced cAMP production in olfactory sensory neurons (OSNs) of Drosophila melanogaster We ...
متن کاملPredicting the response of olfactory sensory neurons to odor mixtures from single odor response
The response of olfactory receptor neurons to odor mixtures is not well understood. Here, using experimental constraints, we investigate the mathematical structure of the odor response space and its consequences. The analysis suggests that the odor response space is 3-dimensional, and predicts that the dose-response curve of an odor receptor can be obtained, in most cases, from three primary co...
