Olfaction is both the simplest and the most complicated of the five senses.
Scientists have uncovered a hidden structure in one of our most mysterious senses. Smell plays a vital role in daily life. It helps us detect danger, enriches the way food tastes,...
The odor receptors in the nose are not distributed at random but organized in a precise spatial pattern, two new studies reveal.
The brain identifies smells in just 50 milliseconds. The olfactory bulb uses "temporal filtering" to lock onto the first scent detected and block out background noise.
A new study unveils a highly organized "smell map" in the nose, driven by retinoic acid gradients and essential for treating anosmia.
Discover how smell receptors in our noses aren’t randomly arranged but are highly organized, offering new paths toward treating sensory impairment.
