During deafness, the visual system takes control of auditory cortex capacity, a phenomenon known as visual take-over. However, how deafness-related compensatory plasticity relates to clinical outcome after cochlear implantation (CI) is not well understood. In an ongoing study, we compared visual evoked potential (VEP) topographies from 12 post-lingually deafened adults using a CI with a sample of 18 normal hearing controls. Visual stimuli were taken from the Multimodal Stimulus Series (cf. www.debener.de) and presented in an audio-visual semantic priming paradigm while EEG was recorded from 68 scalp sites. Inspection of VEP amplitudes and latencies suggested a number of group differences. For instance, P2 amplitudes at midline electrodes revealed a Group x SITE interaction (p<.05) that remained significant after vector normalisation. As predicted, CI users showed a more anterior distribution in the P2 latency range (see supplemental figure). A source-based analysis of the visual take-over phenomenon will be presented and the results will be discussed with regard to the clinical performance of CI users.
