Optimizing estimation of hemispheric dominance for language using magnetic source imaging.
The efficacy of magnetoencephalography (MEG) as an alternative to invasive methods for investigating the cortical representation of language has been explored in several studies. Recently, studies comparing MEG to the gold standard Wada procedure have found inconsistent and often less-than accurate estimates of laterality across various MEG studies. Here we attempted to address this issue among...
متن کاملMagnetic source imaging of late evoked field responses to vowels: toward an assessment of hemispheric dominance for language.
OBJECT The goal of this study was to determine whether the late neuromagnetic field elicited by simple speech sounds, which is detected by magnetoencephalography, may be used to estimate hemispheric dominance for language and to guide or constrain the intraoperative search for essential language sites. If sufficiently robust, a noninvasive method for assessing hemispheric dominance for language...
متن کامل[Hemispheric dominance for language and functional magnetic resonance: a comparison of three tasks].
OBJECTIVE The object of this study to analyse and compare the efficacy of the classic language tasks (repetition, phonological fluency and lexical decision), for the purpose of identifying the dominant hemisphere for language by means of functional magnetic resonance. SUBJECTS AND METHODS The three tasks were performance with a groups of 10 right handed subjects with ages of 22 to 40 years. T...
متن کاملSchizophrenia as failure of hemispheric dominance for language.
Schizophrenic illnesses occur with approximately the same incidence in all human populations with a characteristic distribution (slightly earlier in males) of ages of onset. Given that the predisposition (which presumably is genetic) is associated with a procreative disadvantage why do such illnesses persist? Here it is suggested that these conditions are a manifestation of genetic diversity in...
متن کاملAssessment of hemispheric dominance for receptive language in pediatric patients under sedation using magnetoencephalography
Non-invasive assessment of hemispheric dominance for receptive language using magnetoencephalography (MEG) is now a well-established procedure used across several epilepsy centers in the context of pre-surgical evaluation of children and adults while awake, alert and attentive. However, the utility of MEG for the same purpose, in cases of sedated patients, is contested. Establishment of the eff...
