Functional olfactory evolution in Drosophila suzukii and the subgenus Sophophora
iScience, 2022 Summary: Comparative analyses of multiple genomes are used extensively to examine the gains and losses of chemosensory receptors across the genus Drosophila. However, few studies have delved into functional olfactory characteristics.

Axonal Odorant Receptors Mediate Axon Targeting
Cell Reports, 2019 Summary: In mammals, odorant receptors not only detect odors but also define the target in the olfactory bulb, where sensory neurons project to give rise to the sensory map.

An update on anatomy and function of the teleost olfactory system [PDF]
PeerJ, 2019 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 ...

Enhanced self-administration of the CB1 receptor agonist WIN55,212-2 in olfactory bulbectomized rats: evaluation of possible serotonergic and dopaminergic underlying mechanisms [PDF]
, 2014 Depression has been associated with drug consumption, including heavy or problematic cannabis use. According to an animal model of depression and substance use disorder comorbidity, we combined the olfactory bulbectomy (OBX) model of depression with ...

Chemo- and Thermosensory Responsiveness of Grueneberg Ganglion Neurons Relies on Cyclic Guanosine Monophosphate Signaling Elements [PDF]
, 2011 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 ...

The structural basis of odorant recognition in insect olfactory receptors
Nature, 2021 Olfactory systems must detect and discriminate amongst an enormous variety of odorants1. To contend with this challenge, diverse species have converged on a common strategy in which odorant identity is encoded through the combinatorial activation of ...

Homozygous deletion of six olfactory receptor genes in a subset of individuals with Beta-thalassemia. [PDF]
PLoS ONE, 2011 Progress in the functional studies of human olfactory receptors has been largely hampered by the lack of a reliable experimental model system. Although transgenic approaches in mice could characterize the function of individual olfactory receptors, the ...

Identification of male- and female-specific olfaction genes in antennae of the oriental fruit fly (Bactrocera dorsalis) [PDF]
, 2016 The oriental fruit fly (Bactrocera dorsalis) is a species of tephritid fruit fly, endemic to Southeast Asia but also introduced to many regions of the US, and it is one of the major pest species with a broad host range of cultivated and wild fruits ...

Induction of Associative Olfactory Memory by Targeted Activation of Single Olfactory Neurons in Drosophila Larvae [PDF]
, 2014 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.

The Odorant Receptor-Dependent Role of Olfactory Marker Protein in Olfactory Receptor Neurons
Journal of Neuroscience, 2016 Olfactory receptor neurons (ORNs) in the nasal cavity detect and transduce odorants into action potentials to be conveyed to the olfactory bulb. Odorants are delivered to ORNs via the inhaled air at breathing frequencies that can vary from 2 to 10 Hz in ...
