Olfactory receptors (ORs) are a family of specialized G-protein coupled receptors (GPCRs), primarily located in the nasal olfactory epithelium where they mediate sense of smell. However, some ORs are ...

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 ...

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 ...

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

A map can be a helpful guide, be it on a road trip or while studying sensory function in the body. When neurobiologist Sandeep Robert Datta and his team at Harvard Medical School began collecting gene ...

The floral scent of blooming lavender, the leafy smell of freshly cut grass, and the earthy aroma of the first rain transport most people back to childhood summer memories. Cells called sensory ...

A team of researchers led by Duke University, the University of California San Francisco, and the Beckman Research Institute of the City of Hope have engineered odorant receptors to reveal the ...
