The purpose

- As the left and right hemisphere are specialized for different auditory tasks, the proposed study aims at demonstrating different consequences of right or left-sided deafness for the affected individual. - Furthermore, the question should be answered if auditory deficits and plastic changes can be partially reversed by cochlear implantation of the deaf ear. - Multicenter, prospective, open, non-randomized clinical trial with 5 patients with right-sided and 5 patients with left-sided sensineural deafness. - Pre-operative: Audiometry, Sound Localization Audiometry, PET, EEG/MEG - Comparison of pre-operative investigations with 10 healthy subjects (age and gender matched control group) - Cochlea implantation - Follow-up Visits at 3, 6, 9 and 12 month post-operative: Audiometry, Sound Localization Audiometry, PET, EEG, Questionnaires - Trial with medical device
