Descriptive Information
Brief Title	Developmental Dyslexia and Functional Maturation of Auditory Cortex
Official Title	Not Provided
Brief Summary	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.
