DOI: 10.1002/cne.24887
Abstract: Individual receptor neurons in the peripheral olfactory organ extend long axons into the olfactory bulb forming synapses with projection neurons in spherical neuropil regions, called glomeruli. Generally, odor map formation and odor processing in all… read more here.

DOI: 10.1007/s10886-020-01160-y
Abstract: Antennal olfactory receptor neurons (ORNs) for pheromone-related and plant volatile compounds were identified and characterized in the lucerne weevil, Sitona discoideus (Gyllenhal), using the single sensillum recording technique. Our study using five pheromone-related compounds and… read more here.

DOI: 10.1016/j.bbrc.2018.06.015
Abstract: Olfactory receptors (ORs) are G protein-coupled receptors that mediate olfactory chemosensation, leading to the perception of smell. ORs are expressed in many tissues, but their functions are largely unknown. Here, we show that the olfactory… read more here.

DOI: 10.1016/j.cub.2020.01.049
Abstract: The regulatory mechanisms by which neurons coordinate their physiology and connectivity are not well understood. The Drosophila olfactory receptor neurons (ORNs) provide an excellent system to investigate this question. Each ORN type expresses a unique… read more here.

DOI: 10.1021/acscentsci.1c01495
Abstract: G protein-coupled receptors (GPCRs) conserve common structural folds and activation mechanisms, yet their ligand spectra and functions are highly diverse. This work investigated how the amino-acid sequences of olfactory receptors (ORs)—the largest GPCR family—encode diversified… read more here.

DOI: 10.1038/nn.4444
Abstract: The olfactory system faces a hard problem: on the basis of noisy information from olfactory receptor neurons (the neurons that transduce chemicals to neural activity), it must figure out which odors are present in the… read more here.

Prior activity of olfactory receptor neurons is required for proper sensory processing and behavior in Drosophila larvae

DOI: 10.1038/s41598-018-26825-3
Abstract: Animal responses to their environment rely on activation of sensory neurons by external stimuli. In many sensory systems, however, neurons display basal activity prior to the external stimuli. This prior activity is thought to modulate… read more here.

DOI: 10.1093/chemse/bjac037
Abstract: Humans have significant individual variations in odor perception, derived from their experience or sometimes from differences in the olfactory receptor (OR) gene repertoire. In several cases, the genetic variation of a single OR affects the… read more here.

DOI: 10.1093/genetics/iyab210
Abstract: Procellariiform seabirds rely on their sense of smell for foraging and homing. Both genomes and transcriptomes yield important clues about how olfactory receptor (OR) subgenomes are shaped by natural and sexual selection, yet no transcriptomes… read more here.
