Accounts for poor motor skills, coordination A scientist investigating why those with Down syndrome often have poor balance and motor coordination has found that key eye reflexes are substantially altered. The findings by University of Colorado School of Medicine researcher Alberto Costa, MD, Ph.D., could lead to new tools to assess the effectiveness of new drugs and therapies aimed at improving quality of life for those with this genetic disorder. "People with Down syndrome suffer...

What does it feel like to return to Earth after a long stay in space? Until now, it has been difficult during astronaut training to realistically simulate the dizzying effects the human body can experience. Dr. Steven Moore leads a research group that has developed a Galvanic vestibular stimulation (GVS) system that safely induces the sensory and mobility disturbances commonly experienced by astronauts after returning to Earth's gravity, making it an excellent operational training tool. When...

The Earthquake Machine at Questacon, the National Science and Technology Centre, has been used in groundbreaking research by vision scientists to confirm that instead of working in isolation, our visual and middle-ear systems work together, to give us an improved sense of balance. Led by Dr Mark Edwards and Dr Michael Ibbotson, chief investigators in The Vision Centre and researchers at the Australian National University, this research has opened up various opportunities to future research,...

Dolphins, whales and porpoises have extraordinarily small balance organs, and scientists have long wondered why. Now a study at Washington University School of Medicine in St. Louis has contradicted a leading theory, which held that the animals moved their heads so vigorously that they had to have smaller, less responsive balance organs to avoid overwhelming their senses. Working with a Midwestern zoo and a local rancher, the researchers, led by Timothy E. Hullar, MD, a Washington University...

The phrase "perk up your ears" made more sense last year after scientists discovered how the quietest sounds are amplified in the cochlea before being transmitted to the brain. When a sound is barely audible, extremely sensitive inner-ear "hair cells""”which are neurons equipped with tiny, sensory hairs on their surface"”pump up the sound by their very motion and mechanically amplify it. Richard Rabbitt of the University of Utah, a faculty member in the MBL's Biology of the Inner...

The organs of the inner ear have a direct effect on brain blood flow, independent of blood pressure and CO2 levels in the blood. Researchers writing in the open access journal BMC Neuroscience used a series of human centrifuge experiments to investigate the effects of stimulation of the otoliths and semi-circular canals on cerebrovascular response. Dr. Jorge Serrador, from Harvard Medical School, worked with a team of researchers, including NASA scientists, to carry out the tests. He said,...

An estimated 35 percent of U.S. adults age 40 and older have vestibular dysfunction (inner ear balance disorders), and those who do may have a higher risk of falling, according to a report in the May 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.The vestibular system helps control an individual's balance, according to background information in the article. The two vestibular organs, within the temporal bone at the side and base of the skull, provide input to the...

A full third of American adults, 69 million men and women over age 40, are up to 12 times more likely to have a serious fall because they have some form of inner-ear dysfunction that throws them off balance and makes them dizzy, according to Johns Hopkins experts.Among the other key findings of the three-year survey and study on the subject by the Johns Hopkins team are that a third of this group, or more than 22 million, were unaware of their vulnerability, having had no previous incidents...
