"Many USH patients benefit from cochlear implants, but preservation and a minimal density ... the key to helping Usher 1 patients to respond to cochlear implants and other treatment options ....

MIT: Using touch to help deaf people

Lehigh researcher awarded $1.8 million NIH grant

... circuits function can help develop or improve prosthetic devices such as cochlear implants. These electronic devices substitute for damaged structures in ... Burger. "But without a long history of this kind of research, devices like cochlear implants would never have been developed." ...

Biophysical method may help to recover hearing

... in societies of growing average age. The conventional hearing-aid and cochlear implant technology have only been partially successful in recreating the ... of frequencies where the cochlea malfunctions to neighboring intact cochlear areas. This remapping is performed in such a way that no auditory ...

Brown to host conference on advances in neurotechnology

... format will pair patients and specialists in the following disciplines: cochlear (ear) implants and retinal (eye) prosthetics; spinal cord injuries; deep ... will consist of four interviews, moderated by Palca. They include: cochlear Implants and Retinal Prosthetics Mark S. Humayun, M.D., professor, ...

Texas Medical Center researchers win collaborative grants

... neurons, first in the lab and then in the mammalian ear. They hope to develop an auditory prosthetic that would be superior to currently available cochlear implants and may eventually perform clinical trials with deaf patients at Texas Children's Hospital and The Methodist Hospital. Citing the ...

Study links low-frequency hearing to shape of the cochlea

... sounds, like the booming of a bass drum. This mechanical ordering of response from high to low frequencies works in the same fashion whether the cochlear tube is laid out straight or coiled in a spiral. But Manoussakis calculations predicted that the spiral shape causes the energy in the low-frequency ...

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 ... loss because it may lead to the activation of cochlear stem cells in the inner ear to regenerate new ... for cell replacement, i.e. transplanting these cochlear stem cells into the adult cochlea to affect hair ...

With cochlear implants, earlier use leads to better speech

In contrast, a child of the same age who had a cochlear implant 31 months earlier made more sophisticated ... the earlier a deaf infant or toddler receives a cochlear implant, the better his or her spoken language ...

Sooner is better with cochlear implants, Stanford scientist shows

... cochlear implants allow the deaf to hear. Their brains ... University of Maryland to see if children with cochlear implants were able to meld their newly acquired ... auditory test and found that some children with cochlear implants fuse the visual and auditory aspects of ...

Critical hearing gene helps send auditory messages to brain

... people who are deaf as a result of defects in otoferlin "will benefit from cochlear implants," the researchers said. cochlear implants analyze sound messages and convert them into electrical signals, ...

Carnegie Mellon scientists show brain uses optimal code for sound

... quality compressed digital audio files and designing brain-like codes for cochlear implants, which restore hearing to the deaf. To achieve their results, ... from DVDs to iPods," Lewicki said. "For instance, if we could use a cochlear implant to 'talk' to the auditory nerve in a more natural way via our ...

St. Jude study solves mystery of mammalian ears

... would be if the cells were absent. As sound waves race into the inner ear at hundreds of miles 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 ...

Scientists identify molecular cause for one form of deafness

... that provides structural framework in living cells. F-actin is organized into bundles by espin, 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 ...

Yale researchers find environmental toxins disruptive to hearing in mammals

... as TBT (tributyl tin), because they appear to alter the balance of chloride ions in the outer hair 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 ...

Born with a love of speech

... of her latest research at the annual meeting of the American Association for the Advancement of 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 ...
