Johns Hopkins Medicine - Before the fluid of the middle ear drains and sound waves penetrate for the first time, the inner ear cells of newborn rodents practice for their big debut. Researchers at Johns Hopkins report they have figured out the molecular chain of events that enables the cells to make "sounds" on their own, essentially "practicing" their ability
Case Western Reserve University School of Medicine finding holds promise for repairing damaged hearing. Hearing is made possible when hair bundles protruding from the tops of hair cells capture the energy of sound waves, converting them into electrical signals that stimulate the auditory nerve to the brain. These hair bundles are made up of individual hair-like projections, or stereocilia, which
Scientists at the Institut Pasteur, Inserm, the Collège de France and Pierre & Marie Curie University, working closely with scientists at the University of Auvergne, have recently discovered the function of pejvakin, a molecule that plays a vital role in the hearing system. The absence of this molecule appears to be responsible for noise-induced hearing loss, one of the most
Researchers show that chronic conductive hearing loss leads to cochlear degeneration. Boston, MA, Nov. 18, 2015. Massachusetts Eye and Ear investigators have shown that sound deprivation in adult mice causes irreversible damage to the inner ear. The findings, published in PLOS ONE , suggest that chronic conductive hearing loss, such as that caused by recurrent ear infections, leads to permanent
California Tele-Audiology Program removes barriers to care, ensuring infants get follow-up hearing tests. SACRAMENTO, Calif. — Researchers at UC Davis have shown that the California Tele-Audiology Program (CTP), which provides follow-up diagnostic evaluations for infants who did not pass their initial newborn hearing test, dramatically improves access to audiologists. In a study published in the journal Telemedicine and e-Health, the
Deaf missionary Andrew Foster honored; various pieces from Black Deaf artists on display. The Joseph F. and Helen C. Dyer Arts Center at Rochester Institute of Technology’s National Technical Institute for the Deaf hosts two exhibits this fall and winter. • “Roots Out of a Dry Ground: The Life and Work of Andrew Foster,” which runs through Dec. 18, is
First-of-its-kind study shows kids with hearing loss benefit from early intervention. University of Iowa - Hearing well impacts every area of a child's life -- language and speech development, social skills, and future academic and life success. Yet little research has been conducted which focuses on infants and preschoolers with mild to severe hearing loss to determine what support or
Infants are motivated by hearing themselves. COLUMBIA, Mo. -- 'Dada' is a first word for many babies. Babbling sounds with consonant-vowel repetitions, such as 'dada,' are common among infants once they reach 8 months old; however, these sounds are not prevalent among infants who have profound hearing loss -- that is, until they receive cochlear implants. Now, University of Missouri
Two studies in mice use new technique to provide insight into cell development critical for hearing, balance. NIH/National Institute on Deafness and Other Communication Disorders - Using a sensitive new technology called single-cell RNA-seq on cells from mice, scientists have created the first high-resolution gene expression map of the newborn mouse inner ear. The findings provide new insight into how
Proteins play key role in genes that help auditory hair cells grow. Baltimore, MD, October 15, 2015 -- Almost 40 million Americans suffer from hearing loss. Right now, there is no way to reverse this condition, largely because auditory hair cells, which sense sound and relay that information to the brain, do not regenerate. A new study led by scientists
