Cochlear implants and brain stem implants.
This chapter describes the development of two implantable prosthetic neurostimulators which, in the last 20 years, have revolutionised the management of severe-to-profound sensorineural deafness. We have witnessed their rapid evolution from the realms of esoteric laboratory abstraction, with many critics and little perceived clinical use, to a routine treatment which is safe, effective and, ind...
متن کاملCochlear Implants and Brain Plasticity
Behavioral data indicate the existence of sensitive periods in the development of audition and language. Neurophysiological data demonstrate deficits in the cerebral cortex of auditory-deprived animals, mainly in reduced cochleotopy and deficits in corticocortical and corticothalamic loops. In addition to current spread in the cochlea, reduced cochleotopy leads to channel interactions after coc...
متن کاملCochlear implants and brain plasticity.
Cochlear implants have been implanted in over 110,000 deaf adults and children worldwide and provide these patients with important auditory cues necessary for auditory awareness and speech perception via electrical stimulation of the auditory nerve (AN). In 1942, Woolsey and Walzl presented the first report of cortical responses to localised electrical stimulation of different sectors of the AN...
متن کاملSpeech 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 کاملCochlear implants
Cochlear implants are the first example of a neural prosthesis that can substitute a sensory organ: they bypass the malfunctioning auditory periphery of profoundly-deaf people to electrically stimulate their auditory nerve. The history of cochlear implants dates back to 1957, when Djourno and Eyriès managed, for the first time, to elicit sound sensations in a deaf listener using an electrode im...
