MEF2C, a gene critical for brain development and regulating circuit formation in the brain also plays a significant role in inner ear development. Mutations of MEF2C have previously been linked to ASD. Researchers found mice with only one copy of the MEF2C gene had reduced activity in the auditory nerve.
Researchers say up to 1 billion teens and young adults are at risk of hearing loss as a result of using headphones, earbuds, or attending loud music venues.
For the first time, researchers have captured in near-atomic detail the structure of a key part of the inner ear responsible for hearing. The results could pave the way for developing new treatments for those with hearing impairments.
Researchers have identified an autophagy pathway in hair cells in the ear that's linked to permanent hearing loss that occurs as a result of exposure to aminoglycosides antibiotics in some patients.
Researchers have identified a master gene that programs ear hair cells into either inner or outer cells. The discovery could lead to new treatments to restore hearing loss associated with aging, noise exposure, or as an adverse reaction to medical therapies.
Early exposure to language, whether it's vocalized or sign language, assists with normal brain development in children, researchers report.
Hearing loss was associated with an increased risk of depression in older adults. Those of lower socioeconomic status were twice as likely to report symptoms of depression. However, using hearing aids helped alleviate symptoms of depression.
