Language dominance assessed by functional transcranial Dopplersonograqhy (fTCD) in young children using a picture description paradigm

Background: In contrast to functional magnetic resonance imaging (fMRI), functional transcranial Dopplersonograqhy (fTCD) can easily be applied in young children. However, fTCD paradigms suitable to lateralize language function in this age group are lacking. The aim of this study was to validate a picture description task for language lateralization with TCD in young children Methods 25 healthy right-handed children (6–11 years) were examined. Blood flow velocity was continuously measured during rest and cued descriptions of pictures from children's books using continuous bilateral TCD. The task-related relative…
