Book excerpt: Considerable variability exists in speech perception outcomes after cochlear implantation, particularly in adults with post-lingual hearing loss. Electroencephalography (EEG) studies have demonstrated that the extent of cross-modal plasticity (i.e. competitive take-over of the auditory cortex by the visual cortex), measured by the activity of the visual-evoked potential (VEP) activity in the cortical regions, is significantly correlated with performance measures of speech perception-in-noise. This trend is observed in adults with a cochlear implant (CI) and therefore, it is of interest to understand how cross-modal plasticity changes with time in adults with severe-profound hearing loss once audition is restored with a CI.
