Olfactory Sensitivity in Mammalian Species: A Review
Olfaction enables most mammalian species to detect and discriminate vast numbers of chemical structures called odorants and pheromones. The perception of such chemical compounds is mediated via two major olfactory systems,the main olfactory system and the vomeronasal system, as well as minor systems, such as the septal organ and the Grueneberg ganglion. Distinct differences exist not only among...
متن کاملMammalian Olfactory Receptors
Perception of chemical stimuli from the environment is essential to most animals; accordingly, they are equipped with a complex olfactory system capable of receiving a nearly unlimited number of odorous substances and pheromones. This enormous task is accomplished by olfactory sensory neurons (OSNs) arranged in several chemosensory compartments in the nose. The sensitive and selective responsiv...
متن کاملSex Differences in Olfactory Sensitivity
The reproductive activity of most vertebrates is regulated, at least to some degree, by external stimuli from the ecological and social environments. Classic and well-studied examples include the influences of photoperiod on the seasonal breeding patterns of birds and mammals [1-4] and the effects of conspecific visual and auditory stimulation upon the gonadotropin secretion, ovarian developmen...
متن کاملAn Olfactory Cilia Pattern in the Mammalian Nose Ensures High Sensitivity to Odors
In many sensory organs, specialized receptors are strategically arranged to enhance detection sensitivity and acuity. It is unclear whether the olfactory system utilizes a similar organizational scheme to facilitate odor detection. Curiously, olfactory sensory neurons (OSNs) in the mouse nose are differentially stimulated depending on the cell location. We therefore asked whether OSNs in differ...
متن کاملInformation processing in the mammalian olfactory system.
Recently, modern neuroscience has made considerable progress in understanding how the brain perceives, discriminates, and recognizes odorant molecules. This growing knowledge took over when the sense of smell was no longer considered only as a matter for poetry or the perfume industry. Over the last decades, chemical senses captured the attention of scientists who started to investigate the dif...
