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 ...

Researchers identify critical link in mammalian odor detection

Researchers at the Monell Center and collaborators have identified a protein that is critical to the ability of mammals to smell. Mice engineered to be lacking the Ggamma13 protein in their olfactory receptors were functionally ...

Genetics

Gene switch for odorant receptors

The olfactory sensory neurons in the nasal mucosa perceive the myriad smells in the air with the aid of odorant receptors. Each sensory neuron chooses one and only one receptor gene for expression. The probability that a ...
