Visual processing in the auditory cortex of cochlear - implant users
Cochlear-implants can be used to restore hearing in individuals with profound hearing loss. Currently, more than 200,000 otherwise deaf individuals are benefiting from this technology. However, there is a high degree of variability in performance outcomes across implant users. Our EEG study suggests that this variability is related to reorganisation within the auditory cortex. In particular, ou...
متن کاملTemporal processing in postlingual adult users of cochlear implant.
INTRODUCTION Postlingual adults demonstrate impressive performance in speech recognition in silence after cochlear implant (CI) surgery. However, problems in central hearing abilities remain, which complicates understanding in certain situations, such as in competitive listening and in the perception of suprasegmental aspects of speech. OBJECTIVE To assess the temporal processing abilities in...
متن کاملTemporal Feature Perception in Cochlear Implant Users
For the perception of timbre of a musical instrument, the attack time is known to hold crucial information. The first 50 to 150 ms of sound onset reflect the excitation mechanism, which generates the sound. Since auditory processing and music perception in particular are known to be hampered in cochlear implant (CI) users, we conducted an electroencephalography (EEG) study with an oddball parad...
متن کاملSpectro-temporal cues enhance modulation sensitivity in cochlear implant users.
Although speech understanding is highly variable amongst cochlear implants (CIs) subjects, the remarkably high speech recognition performance of many CI users is unexpected and not well understood. Numerous factors, including neural health and degradation of the spectral information in the speech signal of CIs, likely contribute to speech understanding. We studied the ability to use spectro-tem...
متن کاملCentral Auditory Processing of Temporal and Spectral-Variance Cues in Cochlear Implant Listeners
Cochlear implant (CI) listeners have difficulty understanding speech in complex listening environments. This deficit is thought to be largely due to peripheral encoding problems arising from current spread, which results in wide peripheral filters. In normal hearing (NH) listeners, central processing contributes to segregation of speech from competing sounds. We tested the hypothesis that basic...
