New research that could help improve hearing tests and devices that restore some hearing to the deaf is reported by researchers at the University of Michigan. Inside the ear, a snail-shaped organ called the cochlea takes in pressure information from the eardrum and turns it into nerve impulses that are sent to the brain. A… Read more

The protein TMC1, discovered in 2002, forms a sound- and motion-activated pore that allows the conversion of sound and head movement into nerve signals that travel to the brain, scientists at Harvard Medical School report. The finding ends a 40-year search for the elusive identity of the sensor protein responsible for hearing and balance. Scientists… Read more

Moving the eyes triggers the eardrums to move as well, a new study by Duke University neuroscientists has found. The researchers discovered that keeping the head still but shifting the eyes to one side or the other sparks vibrations in the eardrums, even in the absence of any sounds. Surprisingly, these eardrum vibrations start slightly… Read more

Motor signals in the brain actually sharpen sound perception, and the effect is boosted when we move in rhythm with the sound, new research suggests. It is already known that the motor system, the part of the brain that controls our movements, communicates with the sensory regions of the brain. The motor system controls eye… Read more

Chronic tinnitus is associated with changes in certain networks in the brain, a new study by University of Illinois researchers found. Furthermore, those changes cause the brain to stay more at attention and less at rest. The finding provides patients with validation of their experiences and hope for future treatment options. “Tinnitus is invisible. It… Read more
