Researchers have discovered a new potential contributor to age-related hearing loss, a finding that could help doctors identify people at risk and better treat the condition.
Music has the ability to captivate us; when listeners engage with music, they follow its sounds closely, connecting to what they hear in an affective and invested way. But what is it about music that keeps the audience engaged? A study by researchers from The City College of New York and the University of Arkansas charts new ground in understanding the neural responses to music.
When we listen to loud sounds, our hearing may become impaired for a short time. Researchers at Linköping University, Sweden, have discovered a mechanism that helps to explain how this happens. Their results are presented in the journal Proceedings of the National Academy of Sciences.
Researchers from Ann & Robert H. Lurie Children's Hospital of Chicago present further evidence that deaf children who received cochlear implants (implanted electronic hearing device) before 12 months of age learn to more rapidly understand spoken language and are more likely to develop spoken language as their exclusive form of communication.
One in four older adults say they feel isolated from other people at least some of the time, and one in three say they lack regular companionship, according to a new national poll. Those feelings of loneliness showed up most in people aged 50 to 80 who also reported they had health issues and unhealthy habits. The findings amplify research showing links between chronic loneliness and health issues ranging from memory loss to shorter lives.
Researchers at Rockefeller University characterized a molecular spring attached to the membrane of inner ear cells that converts bending forces created by a sound wave to electrical signals that the brain can interpret.
Studying the songs of mice from the cloud forests of Costa Rica, researchers have identified a brain circuit that might enable the high-speed back and forth of human conversation. This insight could help researchers better understand the causes of speech disorders and point the way to new treatments.
In multicultural areas like San Francisco, doctors are increasingly looking to Google Translate to provide written instructions their patients can take home, so they stand a better chance of following medical advice. But is Translate trustworthy? Researchers at UC San Francisco say the answer is yes -- with some caveats.
The study, conducted at the Center for Mind/Brain sciences at the University of Trento, Italy, shows that small involuntary eye movements, independent of any response, can be used to determine whether one has successfully learned. This finding opens new possibilities in understanding the process of learning in populations that are less responsive to external events, such young children, or individuals with certain mental or physical conditions.
Scientists have managed to restore hearing in an adult mouse model of DFNB9 deafness -- a hearing disorder that represents one of the most frequent cases of congenital genetic deafness. Individuals with DFNB9 deafness are profoundly deaf as they are deficient in the gene coding for otoferlin, a protein which is essential for transmitting sound information at the auditory sensory cell synapses.
