Researchers at Michigan State University have identified a gene mutation linked to hearing loss, which could lead to new insights into the biology of progressive hearing loss. The discovery is expected to provide new avenues for preventing or treating this common health issue, affecting an estimated 28 million Americans.
Researchers found that a mutated fruit fly gene controlling hearing produces similar consequences in humans, including hearing loss and limb deformities. The study suggests that hearing may have evolved earlier than previously thought, linking human genetics to those of fruit flies.
A three-year study found that low-dose methotrexate had no effect on maintaining restored hearing in patients with autoimmune inner ear disease (AIED). Researchers are now focusing on alternative treatments for this rare condition.
Researchers discovered that sensory cells in mouse inner ear develop rapidly between days 16 and 17 of gestation, mirroring human fetal development. Understanding this process is crucial for regenerating sensory hair cells in the human ear.
The video doctor program uses a computer-based multimedia approach to provide personalized advice on reducing smoking and alcohol use. Patients who interacted with the video doctor showed positive responses, but still preferred consultation with real doctors.
Researchers found that musicians remembered music better when they heard it during learning, regardless of whether they heard the music when replayed it later. This contradicts matching theories and suggests that auditory feedback plays a crucial role in music memory.
A team of researchers found that the absence of a specific gene, Ink4d, causes progressive hearing loss in mice by triggering the death of sensory hair cells. This finding suggests that humans with similar genetic mutations may be more susceptible to hearing loss due to trauma.
Researchers have identified three genes, Myosin VIIa, Harmonin, and Cadherin 23, that cooperate to shape the sensory hair cell bundle. These findings provide new insights into Usher syndrome, a genetic disorder affecting vision and hearing.
Researchers have identified a new human hearing loss gene, TMIE, in deaf mice, which may lead to the development of a screening test and therapy for families affected by inherited hearing loss. The discovery brings scientists closer to understanding the intricate choreography of genes and proteins involved in human hearing development.
A new compound is being developed to target specific types of hearing loss, with the goal of repairing and regrowing injured or damaged auditory hair cells. The treatment aims to prevent hearing loss by bolstering the inner ear's antioxidant defenses and may offer hope for some patients with sudden hearing loss.
Researchers found that 6-month-old hearing infants consistently preferred American Sign Language to pantomime. The infants spent more time looking at ASL than pantomime, even when given the freedom to look elsewhere. This study expands on previous findings of infants' sensitivity to spoken language and may indicate a universal preferen...
A new test simulates real-world noise to evaluate children's binaural hearing abilities, which affects learning and concentration in noisy environments. The test assesses how well children can separate competing sounds, with results showing varying ability levels among children.
A landmark study published in Nature reveals that deaf and hearing adults who experienced language in early life perform similarly well in learning a new language later in life. Deaf adults with little language experience show low levels of performance, whereas those with early experience demonstrate high proficiency.
A significant proportion of elderly people in the UK experience poor hearing, with around a quarter failing a whispered voice test. The study highlights challenges in improving detection and management of reduced hearing, as well as increasing ownership and use of hearing aids.
A new study reveals that specific subdivisions of the auditory cortex play a crucial role in identifying fine distinctions in pitch. The research found that subtle manipulations in the brain's response to complex tones can significantly impact our perception of musical nuances.
Researchers found that babies exposed to signed language produce distinct hand movements with low-frequency rhythmic activity, indicating an innate sensitivity to linguistic patterns. This discovery suggests that parents' sing-song way of speaking and playful rhyming games can aid the language learning process.
A recent court decision requiring all North Carolina speech-language pathologists to hold a master's degree may lead to a 13% workforce loss in the state's public school system. The shortage could exacerbate caseloads, particularly for students with autism and growing demands for early intervention services.
A new hearing test called wide-band reflectance could improve diagnosis of middle ear infections and other hearing disorders. The test uses softer sounds to trigger a middle ear reaction, allowing doctors to make a diagnosis without exposing patients to intense noise.
A Northwestern University study found that many older women have undiagnosed and untreated hearing loss, which can lead to depression and emotional problems. The researchers suggest that public policy should include hearing care as part of all health maintenance plans.
A computer model developed by Jay Rubinstein suggests that increasing the signal pulses from external processors can produce more independent neuron activity, similar to natural acoustic stimulation. This breakthrough could lead to substantial improvements in all types of sound coding for people with cochlear implants.
Research suggests that older people's tolerance for rock music is lower due to physiological changes, such as presbycusis, which affects hearing. Additionally, emotional factors play a role in auditory perception, with older adults potentially being more irritated by rock music due to unfamiliarity.
The University at Buffalo's Center for Hearing and Deafness has received a $5.7 million grant to study acquired hearing loss, affecting 28 million people in the US. The center will investigate four projects on peripheral and central auditory system function.
Researchers found that senior citizens rated rock music much higher on a loudness scale than younger people. As people age, their tolerance for loudness decreases due to common hearing loss conditions like presbycusis, which distorts certain sounds and makes low frequencies more noticeable.
A free orientation program developed by UF professor Alice Holmes aims to increase patient satisfaction among hearing aid users. The four-session program provides realistic guidance on using hearing aids, adjusting settings, and preventing communication breakdowns.
Researchers at University at Buffalo found that the brain center responsible for hearing can reorganize itself after damage to the auditory nerve endings. The damaged nerve endings take longer to recover, but the brain recovers sooner, within five days.
Researchers found that R-PIA increased the activity of glutathione, an antioxidant that absorbs free radicals, providing enhanced protection from damage. Animals treated with R-PIA recovered their hearing faster and more completely than those treated with saline, showing less damage to sensory cells.
Researchers found that mice without thyroid hormone receptor beta are deaf, even though they appear healthy. The study suggests that this gene controls hearing development, and its loss may cause human genetic forms of deafness.
