Quantifying how the brain smells
Scientists haven't quite decoded how animals smell, but researchers at Cold Spring Harbor Laboratory (CSHL) found that it's different from previously thought.

An impaired sense of smell can signal cognitive decline, but 'smell training' could help
As we age, we often have problems with our ability to smell (called olfactory dysfunction). Older people might not be able to identify an odour or differentiate one odour from another. In some cases they might not be able ...

Electrical stimulation in the nose induces sense of smell in human subjects
Physicians at Massachusetts Eye and Ear have, for the first time, induced a sense of smell in humans by using electrodes in the nose to stimulate nerves in the olfactory bulb, a structure in the brain where smell information ...

Automated detection of sleep states from olfactory brain waves
Scientists have developed a completely automated technique for real-time detection of sleep/wake states in freely moving mice. Conducted by Karim Benchenane, Sophie Bagur and colleagues at the National Centre for Scientific ...

How clutch molecules enable neuron migration
The brain can discriminate over 1 trillion odors. Once entering the nose, odor-related molecules activate olfactory neurons. Neuron signals first accumulate at the olfactory bulb before being passed on to activate the appropriate ...

Fine-tuned sense of smell relies on timing
If you can tell the difference between a merlot and a cabernet franc just by smell, it's probably all in the timing.

Gene therapy restores sense of smell in mice
Re-expressing a protein critical for the detection and perception of odors restores function of the olfactory system in a genetic mouse model of lost hair-like cellular structures known as cilia, according to research published ...

A rose is a rose is a rose: Mathematical model explains how two brains agree on smells
In a new study, Columbia scientists have discovered why the brain's olfactory system is so remarkably consistent between individuals, even though the wiring of brain cells in this region differs greatly from person to person. ...

Study tracks what moths think when they smell with their antennae
Think of an animal tracking a scent, and you may picture a bloodhound with its nose to the ground. But a moth fluttering through the air is likely smelling for clues, too. Pollinating insects like the hawkmoth track scents ...
