Recent findings

Reading Fluencyis crucial marker of quality of life

Dyslexia = dysfluentreading

Development of corticalnetworkforfluent readingnot well understood

Interventionfailstoimprovefluency

show 2 networks:

Cross-modalintegrationof letters & speech sounds

Visual word recognition(“visual word form area”)

To do

  • Window on the neuraldynamics of the developmentalpathwayfrom novice to expert reader

    • Unravelhowneuraldysfunctionshamper reading fluency in dyslexia

  • Identify succes factors of interventionand break throughnototious “fluencybarrier” in dyslexia

    • How treatment induce changes in the neuraldynamics
