An update on anatomy and function of the teleost olfactory system [PDF]
About half of all extant vertebrates are teleost fishes. Although our knowledge about anatomy and function of their olfactory systems still lags behind that of mammals, recent advances in cellular and molecular biology have provided us with a wealth of ...

The source of spontaneous activity in the main olfactory bulb of the rat. [PDF]
In vivo, most neurons in the main olfactory bulb exhibit robust spontaneous activity. This paper tests the hypothesis that spontaneous activity in olfactory receptor neurons drives much of the spontaneous activity in mitral and tufted cells via ...

Synaptophysin and synaptoporin expression in the developing rat olfactory system [PDF]
The expressions of two closely related synaptic vesicle antigens synaptophysin and synaptoporin were examined in the olfactory system of the adult rat and during pre- and postnatal development.

Expressing exogenous functional odorant receptors in cultured olfactory sensory neurons
Background Olfactory discrimination depends on the large numbers of odorant receptor genes and differential ligand-receptor signaling among neurons expressing different receptors.

Induction of Associative Olfactory Memory by Targeted Activation of Single Olfactory Neurons in Drosophila Larvae [PDF]
It has been postulated that associative memory is formed by at least two sets of external stimuli, CS and US, that are transmitted to the memory centers by distinctive conversing pathways.

Signal Amplification in Drosophila Olfactory Receptor Neurons [PDF]
Olfactory receptor neurons (ORNs) transform scant chemical inputs into significant neural signals. This transformation requires signal amplification. In this issue of Neuron, Ng et al. (2019) identified a mechanism by which the signals evoked by pheromones are amplified in the ORNs that selectively promote courtship behavior in Drosophila.

Signaling by olfactory receptor neurons near threshold [PDF]
An important contributing factor for the high sensitivity of sensory systems is the exquisite sensitivity of the sensory receptor cells. We report here the signaling threshold of the olfactory receptor neuron (ORN). We first obtained a best estimate of the size of the physiological electrical response successfully triggered by a single odorant-binding ...

Cholinergic calcium responses in cultured antennal lobe neurons of the migratory locust
Locusts are advantageous organisms to elucidate mechanisms of olfactory coding at the systems level. Sensory input is provided by the olfactory receptor neurons of the antenna, which send their axons into the antennal lobe. So far, cellular properties of

Chemo- and Thermosensory Responsiveness of Grueneberg Ganglion Neurons Relies on Cyclic Guanosine Monophosphate Signaling Elements [PDF]
Neurons of the Grueneberg ganglion (GG) in the anterior nasal region of mouse pups respond to cool temperatures and to a small set of odorants. While the thermosensory reactivity appears to be mediated by elements of a cyclic guanosine monophosphate ...

Odour Transduction in Olfactory Receptor Neurons
The molecular mechanisms that control the binding of odorant to olfactory receptors and transduce this signal into membrane depolarization are reviewed. They are compared in vertebrates and insects for interspecific (allelochemicals) and intraspecific (pheromones) olfactory signals. Attempts to develop quantitative models of these multistage signalling
