Next-generation cochlear implants on the horizon

A healthy ear is much better at detecting and transmitting sound than even the most advanced hearing aid. But now researchers reporting in the Biophysical Journal, a Cell Press publication, have uncovered new insights into how the ear -- in particular, the cochlea -- processes and amplifies sound. The findings could be used for the development of better devices to improve hearing. Sound-sensing cells within the cochlea -- called hair cells due to the presence of cilia on their membrane surfaces -- vibrate strongly at different sound frequencies depending on their location...
