Scientists in Oregon have discovered that gene therapy may be able to restore working hair cells that are essential for the inner ear to interpret sounds. Writing in the journal Nature, researchers said that these cochlear hair cells send electrical signals to convert sounds and transmit them to the brain. Cochlear cells are naturally irreplaceable. Most people who suffer from hearing loss gradually lose it through the reduction of hair cells in the cochlea. Loud noise is a key contributor...

U.S. scientists say they have grown tiny hair cells that are necessary for hearing, suggesting a new therapy to regain hearing might be possible. The Oregon Health & Science University researchers said they produced functional auditory hair cells in the cochlea of a mouse inner ear. "One approach to restore auditory function is to replace defective cells with healthy new cells," Assistant Professor John Brigande said. "Our work shows that it is possible to produce functional auditory...

Sound Pharmaceuticals has received a R&D contract award from the Office of Naval Research for approximately $1.6 million to optimize its lead drug candidate for hearing regeneration. Sound Pharmaceuticals has developed a proprietary technology for regenerating auditory sensory cells within the inner ear of mammals involving p27Kip1, a cyclin dependent kinase inhibitor or CKI. In 2005, the Office of Naval Research began funding this hearing regeneration project. This new funding brings...

A healthy ear emits soft sounds in response to the sounds that travel in. Detectable with sensitive microphones, these otoacoustic emissions help doctors test newborns' hearing. A deaf ear doesn't produce these echoes. New research involving the University of Michigan and Oregon Health and Science University shows that, contrary to the current scientific thought, the emissions don't leave the ear the same way they entered. The findings give new insight into a phenomenon that researchers study...

(RedOrbit) Yale researchers have found that chloride ions are critical to hearing in mammals and that some environmental toxins may disrupt the balance of these ions in ear cells and therefore disrupt hearing. Joseph Santos-Sacchi, professor in the Departments of Surgery and Neurobiology, and primary author of the study says, "our data are the first to directly show that chloride ions are crucial for our exquisite sense of hearing." Using guinea pig as a model system, Dr. Santos-Sacchi...

ATLANTA - Scientists are one step closer to understanding the genetic pathway involved in the development of hearing. New research findings, published online this week in the journal Nature Genetics, detail how sensory hair cells in the ear "“"“ the cells largely responsible for hearing "“"“ develop unique shapes that enable the perception of sound. Located in the spiraled cochlea, the hearing portion of the inner ear, the hair cells transform the mechanical...

PORTLAND, Ore. "“ Researchers at Oregon Health & Science University's Neurological Sciences Institute and the University of Bologna have developed a portable "Ipod-like" device that can be used to help correct balance disorders. Scientists believe this new device, based on auditory feedback of balance, can be worn on the belt like a pager to provide regular therapy for patients with balance disorders, improving their day-to-day activities. The research is published in the current...

ITHACA, N.Y. -- Cornell University researchers have learned how a common fish found along the West Coast can hum and hear outside sounds at the same time. The study marks the first time that scientists have found a direct line of communication between the part of a vertebrate's brain that controls the vocal muscle system and the part of the ear that hears sound. The researchers believe that understanding the auditory system of the plainfin midshipman fish (Porichthys notatus ) -- a 6- to...

WASHINGTON (AP) -- Researchers have identified a gene that prevents the regeneration of inner ear cells that are critical to hearing, a discovery experts say is the first step toward finding a way to correct the most common form of deafness among the elderly. In laboratory mouse studies at Massachusetts General Hospital, researchers found that by eliminating the effects of a single gene they could cause inner ear cells vital to hearing to regrow. The regrowth replaces nerve endings, called...

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...
