2013-09-27 13:46:12

Brett Smith for redOrbit.com - Your Universe Online Spinning around in circles causes dizziness in most people, which could be a problem for figure skaters or ballerinas who must perform several spins during a typical routine. However, new research in the journal Cerebral Cortex indicates that ballerinas may have conditioned their brain to better handle a series of quick spins. Study researchers said their findings could be used to improve treatments for patients with chronic dizziness....

Is this my finger? People can be easily tricked into believing an artificial finger is their own, shows a study published today [23 September] in The Journal of Physiology. The results reveal that the brain does not require multiple signals to build a picture body ownership, as this is the first time the illusion has been created using sensory inputs from the muscle alone. The discovery provides new insight into clinical conditions where body representation in the brain is disrupted due...

Scientists Categorize Smells Ten Groups
2013-09-19 08:44:34

Michael Harper for redOrbit.com - Your Universe Online Of all the different odors and smells floating around the globe, scientists say humans can only detect ten basic categories of scents. Using a computerized model, sensory scientists now say they've developed a way to systematically categorize these smells. Using a preexisting set of odors and descriptions, the scientists ran them through the computerized model, categorized them, and have now concluded all the world’s smells...

Getting the message about bitter taste Do you love chomping on raw broccoli while your best friend can't stand the healthy veggie in any form or guise? Part of the reason may be your genes, particularly your bitter taste genes. Over the past decade, scientists at the Monell Center and elsewhere have made headway in understanding how variants of bitter taste receptor genes can help account for how people differ with regard to taste perception and food choice. However, some perplexing...
