We recently published an fMRI paper from the Leeswisnt project exploring changes in brain
activation during letter-speech mapping over a three year period in children without dyslexia. Our
findings show that reading development is characterized by dynamic changes in auditory as well
as visual brain areas, and highlight the specific changes to our understanding and processing of
speech that accompany reading acquisition.
