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...

No Hear This! Inner-Ear Membrane Uses Nanopores To Separate Sounds
2014-03-19 04:37:47

redOrbit Staff & Wire Reports - Your Universe Online Computers have been largely unable to duplicate a person’s ability to tune into a single voice, even in the midst of background noise, but new research into the biological mechanisms of the human ear could soon change that. According to researchers from the Massachusetts Institute of Technology (MIT), the ear’s selective hearing is due to the evolution of the tectorial membrane, a tiny membrane located inside the inner ear....

Researchers at King's College London have uncovered how the human ear is formed, giving clues as to why children are susceptible to infections such as glue ear. The work was funded by the UK Medical Research Council and published today in the journal Science. It is estimated that one in five children around the age of two will be affected by glue ear, a build-up of fluid in the middle ear chamber. This part of the ear contains three tiny bones that carry sound vibrations from the eardrum...

Molecule That Converts Sound Into Brain Signals Found
2012-12-07 12:39:03

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
2012-10-03 13:58:43

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...

A Middle-Ear Microphone

Device could make cochlear implants more convenient Cochlear implants have restored basic hearing to some 220,000 deaf people, yet a microphone and related electronics must be worn outside the head, raising reliability issues, preventing patients from swimming and creating social stigma. Now, a University of Utah engineer and colleagues in Ohio have developed a tiny prototype microphone that can be implanted in the middle ear to avoid such problems. The proof-of-concept device has...

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...

(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...

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...
