Sooner is better with cochlear implants, Stanford scientist shows

...the University of Maryland to see if children with cochlear implants were able to meld their newly acquired he...le auditory test and found that some children with cochlear implants fuse the visual and auditory aspects of speech - just like people with normal hearing. But ...

Carnegie Mellon scientists show brain uses optimal code for sound

...tal audio files and designing brain-like codes for cochlear implants, which restore hearing to the deaf. To ...," Lewicki said. "For instance, if we could use a cochlear implant to 'talk' to the auditory nerve in a more natural way via our discovered coding, then we co...

Born with a love of speech

...f Science in St. Louis, February 17th. Neural and cochlear development is such that at about six months gestation the fetus begin to hear a range of frequencies. Thus, there's the possibility that newborns preferentially listen to speech because they're used to it from their in-utero tuning-in. But, which s...

Yale researchers find environmental toxins disruptive to hearing in mammals

...ir cell." Sensitive hearing in mammals relies on cochlear amplification resulting from the motor activity of outer hair cells. They are the only group of animals that have outer hair cells. Additionally, TBT is known to damage the immune and hormonal systems of marine mammals. In this study on guinea pigs...

With cochlear implants, earlier use leads to better speech

... 3 and a half-year old child, born deaf but with a cochlear implant that partially restored hearing nine month.... In contrast, a child of the same age who had a cochlear implant 31 months earlier made more sophisticated statements: "OK, now the people goes to stand ther...

Critical hearing gene helps send auditory messages to brain

... result of defects in otoferlin "will benefit from cochlear implants," the researchers said. Cochlear implants analyze sound messages and convert them into electrical signals, bypassing the cochlea to directly stimulate the auditory nerves. "That's good news," Petit said, since otoferlin-linked deafness is ...

Study shows isolation of stem cells may lead to a treatment for hearing loss

... “Previous work in our lab with young-adult mouse cochlear tissue showed expression of genes normally found i...ring loss because it may lead to the activation of cochlear stem cells in the inner ear to regenerate new hair cells. “Clearly we have miles to go before we re...

Scientists identify molecular cause for one form of deafness

...a linker protein found in sensory cells, including cochlear hair cells. Genetic mutations in espin's F-actin binding sites are linked to deafness in mice and humans. "We found the structure of the bundles changes dramatically when normal espin is replaced with espin mutants that cause deafness," said Gerard...

St. Jude study solves mystery of mammalian ears

... per hour, their energy—although dissipated by the cochlear fluid—generates waves in the fluid, somewhat like the tiny waves made by a pebble thrown into a pond. This energy causes the hair cell cilia in both mammals and non-mammals to swing back and forth quickly in a steady rhythm. In mammals, the rod-sha...
