NIH Researchers Find How Sound Reduces Pain in Mice
An international team of scientists has identified the neural mechanisms through which sound reduces pain in mice, according to an announcement on the National Institutes of Health (NIH) website.

Previously, misophonia had been considered a disorder of sound processing. This new research suggests that alongside this there is an abnormal type of communication between the brain's hearing center, the auditory cortex, and the areas of the ventral pre-motor cortex that are responsible for movement of the face, mouth, and throat.
Studies conducted by Eriksholm Research Centre found that natural brain function first processes the entire sound scene before focusing or selectively attending to the sound of interest. Researchers point out that the findings have significant implications for hearing aid design, challenging traditional approaches that let conventional technology decide what the brain needs to attend to.
The results suggest that facilitating exposure to sounds during early age can restore communication between brain cells that have been altered by the gene mutation that leads to FXS.

Read MoreResearch has shown that people who are born blind or become blind early in life often have a more nuanced sense of hearing, especially when it comes to musical abilities and tracking moving objects in space (imagine crossing a busy road using sound alone). For decades scientists have wondered what changes in the brain might underlie these enhanced auditory abilities.

Read MoreWith a better understanding of cortical brain changes associated with hearing loss, the potential to develop objective brain-based tools (ie, biomarkers) increases. These tools may help clinicians determine when a patient should receive intervention, what kind of intervention or rehabilitation would be ideal, and may offer the ability to monitor how well a chosen intervention or rehabilitation method is working. Prominent researchers Anu Sharma and Hannah Glick explain why.
Read MoreLooking at someone’s lips is good for listening in noisy environments because it helps our brains amplify the sounds we’re hearing in time with what we’re seeing, finds a new University College London (UCL)-led study.
Read MoreA cognitive hearing aid that constantly monitors the brain activity of the subject to determine whether the subject is conversing with a specific speaker in the environment would be a dream come true.
Read MoreHarvard University researchers and colleagues have found that the neural architecture in the auditory cortex—the part of the brain that processes sound—is virtually identical in deaf and hearing people. The study raises new questions about the role of experience in processing sensory information.
Read MoreA study of zebra finches reveals that norepinephrine, a neuromodulator, aids the brain in sorting complex auditory signals for hearing in noisy environments.
