| Popis: | Background:Cochlear implant (CI) users’ enjoyment of music andunderstanding of spoken language depend dependsnot only on hearingsounds but also on distinguishing between them . While soundsensation is typically measured from the auditory brainstem response,no common objective measure has been established for testing sounddiscrimination ability. We here propose t the cortical mismatchnegativity response (MMN) [1] and spike densitity component analysis(SCA) [2] as novel diagnostical tools.Methods:11 experienced CI users and 14 normal hearing controlslistened to the CI MuMufe MMN parad paradig m [1]. MMN responses todeviant tones for 4 sound features each tested at 4 magnitude levelswere measured with electroencephalography (EEG). The individualMMN was automatically detected with SCA statistics. Attentive sounddiscrimination ability was measured with a behavioral test.Results:Automatically detected individual MMN responses predictedCI users’ behavioral sound discrimination ability with high (~90%)accuracy , even for complex music stimuli. SCA statistics, tailored foranalysis on individuals, showed significantly higher diagnosticaccuracy ( p(p=.003) than previous methods inspired by group group-level EEG analysis. |
