TMC1: The Molecular Sensor That Converts Sound Into Brain Signals

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 […]

Eardrum Motion Synchronized With Direction And Amplitude Of Saccades

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 […]

Chronic Tinnitus Keeps The Brain More At Attention

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 […]
