Listening Behavior Affected by Hemisphere Connection
In a neuroimaging study, a team of researchers led by the Max Planck Institute of Psycholinguistics, the Donders Institute, and the University of Zurich applied electrical stimulation to participants’ brains during a listening task. The stimulation affected the connection between the two hemispheres, which in turn changed participants’ listening behavior, according to a summary on the Max Planck website.

USC Stem Cell Study Traces Evolution of Organ of Corti
By the time mice are born, the progenitor cells in the Organ of Corti have finished both proliferation and differentiation, and cannot regenerate if they are damaged—causing permanent hearing loss.
Sensorion Partners with Institut Pasteur on Research Framework Targeting Hearing Loss
Sensorion and Institut Pasteur have leveraged the last six months to reach a partnership framework agreement. This agreement provides for, after completion of a research program, an exclusive option to obtain licenses.

Researchers Identify Brain Regions in Blind Individuals Responsible for Sharpened Auditory Function
Research 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.

Mechanism Associated with Hearing Impairment after Listening to Loud Music Discovered
Until now, scientists have thought that the tiny membrane has a mainly mechanical function, but the discovery made by the LiU researchers suggests that the tectorial membrane may play an important role in regulating hearing by storing calcium.

Researchers Restore Hearing via Gene Therapy in Deaf Mouse Model
Researchers 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

PH Imbalance in Brain Cells May Be Related to Alzheimer’s, Johns Hopkins Research Shows
One root of Alzheimer’s disease may be a simple imbalance in acid-alkaline—or pH—chemistry inside endosomes, the nutrient and chemical cargo shuttles in cells.

Salt- or Sugar-Based Solution May Diminish Noise-Induced Hearing Loss
The researchers found that sensory hair cell death occurred immediately after exposure to loud noise and was irreversible. Neuron damage, however, had a delayed onset, opening a window of opportunity for treatment.

Researchers Identify Protein That May Influence Shape of Ear’s Sensory Hairs
The scientists think Daple influences the shape of the hair bundles indirectly, by determining the position of the first filament to emerge at what becomes the apex of each bundle.

Researchers Study Sound Quality of Spider Silk
Would you want a spider web inside your ear? Probably not. But if you’re able to put aside the creepy factor, new research shows that fine fibers like spider silk actually improve the quality of microphones for hearing aids.

Lip Reading May be Beneficial to Hearing Ability for CI Users, NIHR Researchers Find
The study reportedly found that, in contrast to existing theory, the more a person’s brain became responsive to lip reading the more it also became responsive to sounds delivered through their CI, and the better they were able to hear.

Study Confirms Our Brains Interpret Sign Language As a Language
There has been debate as to what role sign language has played in language evolution, and whether the structure of sign language shares similarities with spoken language. New research shows that our brains detect deep similarities between speech and sign language–interpreting both equally as language.

Auditory Speech Perception Requires Tongue Movement
Researchers at the University of British Columbia have found that babies need free tongue movement to decipher speech sounds, and the study is the first to discover a direct link between infants’ oral-motor movements and auditory speech perception.

How Noise Exposure Alters the Brain
Researchers have found that, in mice, prolonged noise exposure altered cells connected to the brain, and it’s likely that synapses become enlarged in noise exposure to create space for chemicals that deliver messages to the brain.
