Olfactory neurons adapt to the surrounding environment

Olfactory receptors, present on the surface of sensory neurons in the nasal cavity, recognize odorant molecules and relay this information to the brain. How do these neurons manage to detect a large variability of signals ...

Exposure to smells in early infancy can modulate adult behavior

Imprinting is a popularly known phenomenon, wherein certain animals and birds become fixated on sights and smells they see immediately after being born. In ducklings, this can be the first moving object, usually the mother ...

Smelling with your tongue

Scientists from the Monell Center report that functional olfactory receptors, the sensors that detect odors in the nose, are also present in human taste cells found on the tongue. The findings suggest that interactions between ...

What's that smell? Scientists find a new way to understand odors

Every smell, from a rose to a smoky fire to a pungent fish, is composed of a mixture of odorant molecules that bind to protein receptors inside your nose. But scientists have struggled to understand exactly what makes each ...

A 'time switch' in the brain improves sense of smell

When the brain processes olfactory stimuli, it differentiates between similar smells using subtly modulated signals. Brain examinations and behavioral studies in mice have now shown that neurons with inhibiting characteristics ...

Key regulatory role for mysterious olfaction molecule OMP

New research from the Monell Center reveals that olfactory marker protein (OMP), a molecule found in the cells that detect odor molecules, plays a key role in regulating the speed and transmission of odor information to the ...
