A team of chemical and biological engineers at Seoul National University in the Republic of Korea has developed a proof-of-concept device that could one day lead to the creation of an artificial nose.

The human olfactory system discriminates between thousands of odors by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different ...

A new study published in Nature reveals how olfactory sensory neurons (OSNs) achieve extraordinary precision in selecting which genes to express. The mechanism is surprising in that it involves ...

The way that the sense of smell works is that olfactory sensory neurons (OSNs) are wired up to olfactory receptors (ORs) in the nasal epithelium, from which they send signals to the brain. Once ...

The human olfactory system discriminates between thousands of odours by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different ...

A new study published in Cell titled, “A spatial code governs olfactory receptor choice and aligns sensory maps in the nose and brain,” led by researchers from Harvard Medical School (HMS) has created ...

From the ability to detect the smell of wet soil to the scent of ripe fruit, the human olfactory system has evolved over thousands of years in response to how people live and what they eat, according ...

Animal reproduction is supported by the integration of various external and internal processes. These processes include a combination of perceived sensory cues, behaviors and hormone secretion. In ...
