Researchers have discovered that specialized proteins in the nose called olfactory receptors can bind with multiple odor molecules, creating a unique 'fingerprint' that the brain understands as a particular smell. This discovery could lead to new fragrances and flavors, as well as artificial smell sensors.
Researchers at Rockefeller University have elucidated the wiring diagram of the accessory olfactory system, which is more complex than the main olfactory system. The findings suggest that the accessory olfactory system recognizes blends of molecules rather than individual odorant molecules.
Scientists discover that the sense of smell in mammals uses a combinatorial code to recognize and process odors, allowing for the detection of thousands of scents with relatively few odor receptors. The study reveals that different combinations of receptors are used to describe various smells.
Linda Buck and colleagues found that the olfactory system uses a combination of odorant receptors to recognize different odors. The nose can discriminate a vast number of diverse odorants by recognizing distinct combinations of receptors.
Researchers have discovered a new method to deliver drugs directly to the brain using nose drops, potentially treating Alzheimer's disease, Parkinson's disease, and multiple sclerosis. The treatment uses nerve growth factor and has shown promising results in animal studies.
Researchers at Caltech found that the brain uses temporal activity patterns of neurons to represent odors, with specificity arising from considerations of their timing. This coding principle may be common to most animals, including humans, and could have implications for understanding odor perception.
