Use of functional MR to map language in multilingual volunteers.

چکیده
PURPOSE To use functional MR imaging to compare brain activation during processing of languages in which multilingual volunteers are fluent with brain activation during processing of languages in which they are not fluent. METHODS Echoplanar images were obtained for five right-handed male multilingual subjects who performed a language task in three languages, one of which was a language in which the subject was not fluent. The functional MR technique included echoplanar images obtained at 1 per second during cycles of rest and performance of the task, from which functional images were processed by means of cross-correlation analysis. The numbers of active pixels in each volunteer and for each language were compared. RESULTS Activation was noted in the left frontal lobe in all subjects performing language tasks. In each subject, the number of activated pixels was greatest for the language in which the subject was least fluent. CONCLUSION Functional MR imaging shows differences in the processing of different languages in multilingual volunteer subjects, depending on the level of fluency in the language, and it is an effective functional imaging method for studying the processing of different languages.

Hemispheric language dominance studied with functional MR: preliminary study in healthy volunteers and patients with epilepsy.
PURPOSE We used functional MR imaging to compare hemispheric language dominance in healthy volunteers and in patients with epilepsy. METHODS We retrospectively reviewed the functional MR images of 23 healthy volunteers and 16 patients with epilepsy obtained by using an echo-planar technique designed for whole-brain imaging. The activation paradigm used was a silent word generation task. Hemis...
متن کاملBilinguality vs. Monolinguality among Kalhuri Kurdish Speakers: Gender, Social Class and English Language Achievement
Today in multilingual contexts, many parents prefer to rear their children in the dominant language rather than in their mother tongue. This phenomenon is widespread among native speakers of Kalhuri dialect of the Kurdish language in the multilingual context of Iran, too. Nevertheless, some studies have evidenced the privilege of bilinguals in learning an additional language though some others ...
متن کاملUsing functional magnetic resonance imaging (fMRI) to explore brain function: cortical representations of language critical areas
Pre-operative determination of the dominant hemisphere for speech and speech associated sensory and motor regions has been of great interest for the neurological surgeons. This dilemma has been of at most importance, but difficult to achieve, requiring either invasive (Wada test) or non-invasive methods (Brain Mapping). In the present study we have employed functional Magnetic Resonance Imaging...
