Discovery May Point to Way to Restore Hearing Loss Caused by Sound, Age Charlottesville, VA (PRWEB) May 20, 2014 The ability to discern pitch – to hear the difference between “cat,” “bat” and “hat,” for example – hinges on remarkable gradations in specialized cells within the inner ear. New research from the University of Virginia School of Medicine and the National Institute on Deafness and Communication Disorders has explained, for the first time, what controls these...

Young Researcher Invited to Present Findings at the American Junior Academy of Science’s Annual Meeting in Chicago. Teen credits University School for Propelling His Interest in Science and Research. Hunting Valley, Ohio (PRWEB) October 31, 2013 Who would have thought that a tiny fish could play such a big role in medical research? University School senior Andrew “Drew” Megerian certainly knows. Using the minnow-sized zebrafish in his research, Drew is working with Dr. Brian...

Mechanism offers potential for interventions that could save hearing A team of NIH-supported researchers is the first to show, in mice, an unexpected two-step process that happens during the growth and regeneration of inner ear tip links. Tip links are extracellular tethers that link stereocilia, the tiny sensory projections on inner ear hair cells that convert sound into electrical signals, and play a key role in hearing. The discovery offers a possible mechanism for potential...

Molecule That Converts Sound Into Brain Signals Found

April Flowers for redOrbit.com - Your Universe Online Finding the exact genetic code that programs the ear´s machinery for responding to sound waves and converting them into electrical impulses in the inner ear has been something of a holy grail for the scientists who study the genetics of hearing and deafness. A new study from The Scripps Research Institute (TSRI) has brought this search to fruition by identifying a critical component of the ear-to-brain conversation. This...

Researchers Look To Understand How The Inner Ear Works

Michael Harper for redOrbit.com — Your Universe Online The workings of the inner ear have been long thought to be well documented and understood. Previous research has found that tiny hairs, known as stereocilia, are attached to sensory cells in the inner ear and move side to side with the reverberations of sound, transferring this sound into the ear, where it is then picked up and translated by the brain. In an effort to better understand these movements and how they are...

Hearing Loss Gene Discovered

redOrbit Staff & Wire Reports - Your Universe Online A team of researchers, led by members of the University of Cincinnati (UC) and Cincinnati Children's Hospital Medical Center, have reportedly discovered a new genetic mutation that leads to deafness and hearing loss associated with a relatively rare condition. In a September 30 press release, lead investigator and UC assistant professor of ophthalmology Zubair Ahmed explain that he and his colleagues were "able to pinpoint the...

The hair cells of the inner ear have a previously unknown "root" extension that may allow them to communicate with nerve cells and the brain to regulate sensitivity to sound vibrations and head position, researchers at the University of Illinois at Chicago College of Medicine have discovered. Their finding is reported online in advance of print in the Proceedings of the National Academy of Sciences. The hair-like structures, called stereocilia, are fairly rigid and are interlinked at their...

From tracking activities within bacteria to creating images of molecules that make up human hair, several experiments have already demonstrated the unique abilities of the revolutionary imaging technique called multi-isotope imaging mass spectometry, or MIMS, developed by researchers at Brigham and Women's Hospital (BWH). MIMS can produce high-resolution, quantitative three-dimensional images of stable isotope tags within subcellular compartments in tissue sections or cells. With its use...

(Ivanhoe Newswire) — Mutated genes in the sensory hair cells of the inner ear prevent sound waves from being converted into electrical signals- a fundamental first step in hearing. Restoring electrical signals in the sensory cells of deaf mice by introducing new genes allowed the mice to hear. The study paves the way for a test of gene therapy to reverse a type of deafness. Sound waves produce the sensation of hearing by jiggling protruding hair-like structures on sensory hair...

Gene-therapy trial will attempt to restore hearing in deaf mice Researchers have found long-sought genes in the sensory hair cells of the inner ear that, when mutated, prevent sound waves from being converted to electric signals — a fundamental first step in hearing. The team, co-led by Jeffrey Holt, PhD, in the department of otolaryngology at Children´s Hospital Boston, and Andrew Griffith, MD, PhD, of the NIH´s National Institute on Deafness and other Communication...
