Need for new cochlear implant design for localizing sound directions

Cochlear implants help deaf patients in hearing, yet the current technology remains far from perfect. A research team led by scientists from City University of Hong Kong (CityU) has shown that neonatally deafened rats could be trained with cochlear implant stimulation to restore the ability to locate the directions of sound origins. The finding implies that shortcomings in current cochlear implant technology, rather than the lack of auditory experience in early childhood, maybe the reason why cochlear implant patients usually have poor spatial hearing performance.
