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 ...

Tsukuba, Japan—Animals, including humans, rely on their sense of smell to locate food, avoid predators, and communicate. This sensory ability depends on specialized receptor proteins. In vertebrates, ...

Our noses encounter a vast diversity of chemicals every day, but scientists know little of how odorants stir awake the receptors in our bodies. A recent study is the first to parse the structure of a ...

For the first time, researchers have determined how a human olfactory receptor captures an airborne scent molecule, the pivotal chemical event that triggers our sense of smell. Whether it evokes roses ...

Firmenich International has patented a high-throughput assay system for identifying compounds that enhance olfactory receptor activity, intensifying the perception of target odorant compounds. The ...

In a recent article published in Scientific Reports, researchers investigated the changes in olfactory bulb volume and structural connectivity of the brain in patients with olfactory dysfunction (OD) ...
