Cross-modal reorganization and speech perception in cochlear implant users.
Recent work suggests that once the auditory cortex of deaf persons has been reorganized by cross-modal plasticity, it can no longer respond to signals from a cochlear implant (CI) installed subsequently. To further examine this issue, we compared the evoked potentials involved in the processing of visual stimuli between CI users and hearing controls. The stimuli were concentric circles replaced...
متن کاملCortical reorganization in postlingually deaf cochlear implant users: Intra-modal and cross-modal considerations
With the advances of cochlear implant (CI) technology, many deaf individuals can partially regain their hearing ability. However, there is a large variation in the level of recovery. Cortical changes induced by hearing deprivation and restoration with CIs have been thought to contribute to this variation. The current review aims to identify these cortical changes in postlingually deaf CI users ...
متن کاملCross-Modal and Intra-Modal Characteristics of Visual Function and Speech Perception Performance in Postlingually Deafened, Cochlear Implant Users.
Evidence of visual-auditory cross-modal plasticity in deaf individuals has been widely reported. Superior visual abilities of deaf individuals have been shown to result in enhanced reactivity to visual events and/or enhanced peripheral spatial attention. The goal of this study was to investigate the association between visual-auditory cross-modal plasticity and speech perception in post-lingual...
متن کاملAuditory cross-modal reorganization in cochlear implant users indicates audio-visual integration
There is clear evidence for cross-modal cortical reorganization in the auditory system of post-lingually deafened cochlear implant (CI) users. A recent report suggests that moderate sensori-neural hearing loss is already sufficient to initiate corresponding cortical changes. To what extend these changes are deprivation-induced or related to sensory recovery is still debated. Moreover, the influ...
متن کاملPerception and Psychoacoustics of Speech in Cochlear Implant Users
Cochlear implants (CIs) are prosthetic devices that restore hearing in deaf individuals via electric stimulation of the auditory nerve through an electrode array inserted in the cochlea. The device consists of a microphone and an externally worn speech processor that converts acoustic signals into electric signals. The speech signal coded with electric pulses is then delivered via a wireless tr...
