Speech Perception in Children with Cochlear Implants
Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...
متن کاملRestoration of auditory nerve synapses in cats by cochlear implants.
Congenital deafness results in abnormal synaptic structure in endings of the auditory nerve. If these abnormalities persist after restoration of auditory nerve activity by a cochlear implant, the processing of time-varying signals such as speech would likely be impaired. We stimulated congenitally deaf cats for 3 months with a six-channel cochlear implant. The device used human speech-processin...
متن کاملEmotional Perception of Music in Children with Unilateral Cochlear Implants
Introduction: Cochlear implantation (CI) improves language skills among children with hearing loss. However, children with CIs still fall short of fulfilling some other needs, including musical perception. This is often attributed to the biological, technological, and acoustic limitations of CIs. Emotions play a key role in the understanding and enjoyment of music. The present study aimed to in...
متن کاملBiomaterials in cochlear implants
The cochlear implant (CI) represents, for almost 25 years now, the gold standard in the treatment of children born deaf and for postlingually deafened adults. These devices thus constitute the greatest success story in the field of 'neurobionic' prostheses. Their (now routine) fitting in adults, and especially in young children and even babies, places exacting demands on these implants, particu...
متن کاملAn evaluation of per-scalar cochlear electrode implantation techniques. An histopathological study in cats.
This study was carried out to evaluate the effects of infection and trauma on the organ of Corti and spiral ganglion cells following per-scalar cochlear electrode implantations in cats. The results showed that the incidence of infection with a per-scalar electrode inserted through an opening made directly into the apical and middle turns is low, provided the procedure is carried out aseptically...
