Abstract *

<p>It is well established that the left hemisphere is dominant in oral language in the majority of neurotypical individuals, while a more symmetrical pattern of activation in shown in cases of language disorders, such as dyslexia. Cerebral lateralization of written language, however, despite the critical role of writing in education and in everyday communication and the fact that children with dyslexia present with writing difficulties, has been investigated by only a few studies, non of which has sampled children, neurotypical or not. Here we aim to investigate the cerebral lateralization of written language in children at risk for dyslexia compared to neurotypical children using functional Transcranial Doppler ultrasonography. We hypothesize that the linguistic component of writing will be less lateralized in children at risk for dyslexia compared to controls. Furthermore, we will explore the correlation between writing competence and the cerebral lateralization of the linguistic component of written language. Findings have potential implications for the use of cerebral lateralization of written language as an early biomarker of dyslexia.</p>
