The old saying, "never put anything smaller than your elbow in your ear," couldn't be truer for a patient who experienced vertigo and severe hearing loss after a cotton swab perforated her eardrum and damaged her inner ear. But what makes this patient's case unique is that otolaryngologists at Henry Ford Hospital in Detroit were not only able to alleviate her vertigo with surgery, but restore her hearing "“ an extremely rare occurrence. "This case is rare because the goal of surgery is...

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,...

GUMC researchers: If a healthy noise cancellation system is restored within the brain, it may be possible to treat the disorder -- the most common auditory disorder in adults About 40 million people in the U.S. today suffer from tinnitus, an irritating and sometimes debilitating auditory disorder in which a person "hears" sounds, such as ringing, that don't actually exist. There isn't a cure for what has long been a mysterious ailment, but new research suggests there may, someday, be a way to...

An in vivo study shows for the first time that there is a stress-response system within the cochlea that mirrors the signaling pathways of the body's fight or flight response. Researchers have identified a hormone-like signaling system of the inner ear that sets baseline hearing sensitivity and helps protect against noise-induced hearing loss. "Our research shows, for the first time, that the cochlea's protective mechanism is likely to be largely a locally-produced phenomenon. The current...

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...

Johns Hopkins scientists show how tiny cells deliver big sound Deep in the ear, 95 percent of the cells that shuttle sound to the brain are big, boisterous neurons that, to date, have explained most of what scientists know about how hearing works. Whether a rare, whisper-small second set of cells also carry signals from the inner ear to the brain and have a real role in processing sound has been a matter of debate. Now, reporting on rat experiments in the October 22 issue of Nature, a Johns...

The fossil of a previously unknown chipmunk-sized mammal was discovered by researchers in north eastern China, who believe it could lead to a better understanding of how human hearing evolved. The team of paleontologists found the 123-million-year-old creature, which is just five inches long, in fossil-rich Liaoning Province, close to where China borders North Korea. "What is most surprising, and thus scientifically interesting, is the animal's inner ear," said Zhe-Xi Luo, a curator at the...

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,...

New technology to hear vibrations through the skull bone has been developed at Chalmers University of Technology. Besides investigating the function of a new implantable bone conduction hearing aid, Sabine Reinfeldt has studied the sensitivity for bone conducted sound and also examined the possibilities for a two-way communication system that is utilizing bone conduction in noisy environments.A new Bone Conduction Implant (BCI) hearing system was investigated by Sabine Reinfeldt:"This hearing...

The ear is an organ from the auditory system that collects sounds, and also balances and enables body position. Formation and Orientation The ear can be broken down into the inner and outer ears. The outer part of the ear is the visible flap (auricle) and ear canal which collects sounds which create pressure that echoes through the middle ear. The inner ear, however, is embedded in the temporal bone. There are hollow areas of the inner ear that are filled with liquids and hair cells...
