To date, it has been unknown exactly how mammals are capable of sniffing out whether a conspecific is ill. The biologists Prof. Marc Spehr and Daniela Flügge are following a good lead. They have discovered ...
Brain encodes complex plumes of odors with a simple code

Your nostrils may seem to be a happy pair, working together to pick up scents. However, a study published online on August 20th in Current Biology reveals that there can actually be a kind of rivalry betwee ...
Impaired sense of smell may be early indicator of Parkinson's disease
Mar 20, 2008 |
4.3 / 5 (4) |
0
Impaired sense of smell occurs in the earliest stages of Parkinson’s disease (PD) and there is mounting evidence that it may precede motor symptoms by several years, although no large-scale studies had confirmed this. In ...
Steroids in female mouse urine light up nose nerves of male mice

A group of steroids found in female mouse urine goes straight to the male mouse's head, according to researchers at Washington University School of Medicine in St. Louis. They found the compounds activate nerve cells in the ...
Study on olfactory nerve cells shows why we smell better when we sniff
Mar 13, 2007 |
4.5 / 5 (6) |
0
Unlike most of our sensory systems that detect only one type of stimuli, our sense of smell works double duty, detecting both chemical and mechanical stimuli to improve how we smell, according to University ...

For the first time, researchers have demonstrated that the efficient coding principle regarding neurobiological processes applies to sense of smell. The team, comprised of researchers from the Czech Academy of Sciences and ...
When smell cells fail they call in stem cell reserves
