Noninvasive Determination of Language Lateralization by Functional Transcranial Doppler Sonography
Background and Purpose—Functional transcranial Doppler ultrasonography (fTCD) can assess event-related changes in cerebral blood flow velocities and, by comparison between sides, can provide a measure of hemispheric perfusional lateralization. It is easily applicable, insensitive to movement artifacts, and can be used in patients with less than perfect cooperation. In the present study we inves...
متن کاملInvestigating language lateralization during phonological and semantic fluency tasks using functional transcranial Doppler sonography
Although there is consensus that the left hemisphere plays a critical role in language processing, some questions remain. Here we examine the influence of overt versus covert speech production on lateralization, the relationship between lateralization and behavioural measures of language performance and the strength of lateralization across the subcomponents of language. The present study used ...
متن کاملReproducibility of functional transcranial Doppler sonography in determining hemispheric language lateralization.
BACKGROUND AND PURPOSE Since functional transcranial Doppler ultrasonography (fTCD) allows convenient and fully automated quantification of language lateralization, it seems ideal for longitudinal studies of perfusion changes during deterioration as well as recovery of language functions. However, during serial examinations, the technical, stochastic, and physiological variabilities of cerebral...

متن کاملLanguage lateralization of hearing native signers: A functional transcranial Doppler sonography (fTCD) study of speech and sign production
Neuroimaging studies suggest greater involvement of the left parietal lobe in sign language compared to speech production. This stronger activation might be linked to the specific demands of sign encoding and proprioceptive monitoring. In Experiment 1 we investigate hemispheric lateralization during sign and speech generation in hearing native users of English and British Sign Language (BSL). P...
