Animals depend on their sense of smell to locate food, identify mates and evade danger. In mammals, olfactory perception typically relies on G protein–coupled receptor (GPCR) pathways. Insects, by ...

Neural waves of three distinct registers combine to give the brain a picture of what's being smelled, according to a Northwestern Medicine study published in PLOS Biology. This is a full ...

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 ...

Rendering the invisible visible is among scientists' favorite challenges. In their efforts to uncover how the olfactory system makes sense of thousands of otherwise invisible odors, scientists now ...

Scientists have quantified and mapped the functional units of the olfactory center in the brains of vinegar flies responsible for the perception of odors. The basic units of the olfactory system in ...

Visualization of the odor discrimination process by an XAI-assisted olfactory sensor. Depending on the odorant molecule, the AI identifies the most responsive receptor materials and highlights the key ...
