Language lateralization represented by spatiotemporal mapping of magnetoencephalography.
BACKGROUND AND PURPOSE Determination of hemispheric language dominance is critical for planning epilepsy surgery. We assess the usefulness of spatiotemporal source analysis of magnetoencephalography for determining language laterality. MATERIALS AND METHODS Thirty-five patients with epilepsy were studied. The patients performed a semantic word-processing task during MEG recording. Epochs cont...
متن کاملVerbal memory and verbal fluency tasks used for language localization and lateralization during magnetoencephalography
OBJECTIVE The aim of this study was to develop a presurgical magnetoencephalography (MEG) protocol to localize and lateralize expressive and receptive language function as well as verbal memory in patients with epilepsy. Two simple language tasks and a different analytical procedure were developed. METHODS Ten healthy participants and 13 epileptic patients completed two language tasks during ...
متن کاملFunctional Neuroimaging of Language Using Magnetoencephalography.
Magnetoencephalography (MEG) is a novel functional brain mapping technique capable of non-invasively measuring neurophysiological activity based on direct measures of the magnetic flux at the head surface associated with the synchronized electrical activity of neuronal populations. Among the most actively sought applications of MEG has been localization of language-specific cortex. This is in p...
متن کاملMeasuring language lateralisation with different language tasks: a systematic review
Language lateralisation refers to the phenomenon in which one hemisphere (typically the left) shows greater involvement in language functions than the other. Measurement of laterality is of interest both to researchers investigating the neural organisation of the language system and to clinicians needing to establish an individual's hemispheric dominance for language prior to surgery, as in pat...
متن کاملthe relationship among efl learners’ autonomy, first language essay writing tasks and second language essay writing tasks in task/content based language instruction
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
