  Purpose
Developmental dyslexia is a frequent learning disability. The aim of this study is to compare auditory evoked cortical responses to syllables and tones in developmental dyslexia and controls (paired with age, gender). The study is conducted in 3 groups of subjects :8-10 years ; 11-17 years and 18-25 years. We suppose that cortical responses should be different in developmental dyslexia and controls.
