Neuroscientists discover new cell type that may help brain maintain memories of smells

Neuroscientists at Case Western Reserve University School of Medicine have discovered a new cell type in the part of the brain that processes our sense of smell. This new cell type, the Blanes cell, is a member of a group of previously unstudied brain cells described by the Spanish neuroanatomist Blanes (pronounced blon ?es) in the late 1800s. Blanes cells have unusual properties which may help...

Researchers show how brain decodes complex smells

Duke University Medical Center researchers have discovered how the brain creates a scent symphony from signals sent by the nose. In studies in mice, the researchers found that nerve cells in the brain's olfactory bulb -- the first stop for information from the nose -- do not perceive complex scent mixtures as single objects, such as the fragrance of a blooming rose. Instead, these nerve ce...

New research shows sharks use their noses and bodies to locate smells

Sharks are known to have a keen sense of smell, which in many species is critical for finding food. However, according to new research from Boston University marine biologists, sharks can not use just their noses to locate prey; they also need their skin – specifically a location called the lateral line. The lateral line is an organ used by all fish to detect, with exquisite sensitivity, movem...

Branding smells

All of a sudden, there is a rush to secure a copyright on any distinct smell from our daily lives, and exclusively use it in conjunction with a branded product or a service. Like the smell of bread in a hot oven at the bakery to be used by a sandwich maker, or the smell of Gouda cheese and the notorious whiff of dirty socks, to be exclusively used by a shoe maker.<b...

Researchers Discover How We Differentiate Smells

You don’t need to sign up for pricey wine appreciation classes to parse the subtle difference between the black cherry bouquet of a pinot noir and the black currant// scent of a cabernet sauvignon. Just pour yourself a couple glasses and sniff. Your brain will quickly help you become a modest oenophile. It’s up to you if you want to drink the lesson plan. A new study by Northwestern Un...

Inability to Recognize Familiar Smells Could Signal Alzheimers

People who have difficulty recognizing familiar smells could be experiencing an early sign of Alzheimer's disease, according to a study published Monday. Scientists already know that the first lesions of the degenerative brain disease tend to show up in an area of the brain that is home to olfactory senses. Doctors at the Rush University Medical Center in Chicago test...
