Olfactory perception plays an important role in food flavor. Humans have around 400 odorant receptors (ORs), which can be activated by an enormous number of odorants in a combinatorial fashion. To date, only a few odorant ...

Olfactory chemotransduction involves a signaling cascade. In addition to triggering transduction, odors suppress ion conductances. By stimulating with brief odorant pulses, we observed a current associated with odor-induced ...

We performed a study on a sample of 856 individuals to answer whether the pleasantness/unpleasantness of the odor perception of their partners (rating of partner odor) is associated with depression and anxiety. To evaluate ...

Triatomines, vectors of Chagas Disease, are hematophagous insects. Efforts have been made to develop synthetic attractants based on vertebrate odor—to lure them into traps. However, because those lures are not practical ...

Several blood-feeding (hematophagous) insects are vectors of a number of diseases including dengue, Chagas disease and leishmaniasis which persistently affect public health throughout Latin America. The vectors of those ...

Áreas residenciais cada vez mais próximas as estações de tratamento de esgotos (ETE) trazem reclamações acerca das emissões odorantes e expõem seus impactos na população. A intensidade e o espalhamento dos odores decorrentes ...

In many pollinating insects, foraging preferences are adjusted on the basis of floral cues learned at the foraging site. In addition, olfactory experiences gained at early adult stages might also help them to initially ...

Vertebrate olfactory receptor neurons (ORNs) exhibit odor-induced increases in action potential firing rate due to an excitatory cAMP-dependent current. Fish and amphibian ORNs also give inhibitory odor responses, manifested ...
