“…The LH region generally responsible for phonological output is the left frontal operculum (Alexander, Naeser, & Palumbo, 1990;Hajek, Valavanis, Yonekawa, Schiess, Buck, & Wieser, 1998;Rosen, Fiez, Hanlon, Dromerick, Linenweber, Petersen, Raichle, & Corbetta, 1998). As discussed above, the RH hypothesis leaves open the question of the laterality of phonological output mechanisms for reading aloud in deep dyslexia.…”

“…The determination of language dominance has become an important issue in the presurgical benefit-risk evaluation of patients with brain tumors in eloquent areas and/ or intractable epilepsy (Loring et al 1990;Gerschlager et al 1998;Hajek et al 1998). An adequate evaluation demands techniques that are reliable, reproducible, repeatable, and risk-free in nature, i.e., in the best case non-invasive.…”

Non-invasive regime for language lateralization in right and left-handers by means of functional MRI and dichotic listening

et al. 2002

Language lateralization was assessed by two independent functional techniques, fMRI and a dichotic listening test (DLT), in an attempt to establish a reliable and non-invasive protocol of dominance determination. This should particularly address the high intraindividual variability of language lateralization and allow decisionmaking in individual cases. Functional MRI of word classification tasks showed robust language lateralization in 17 right-handers and 17 left-handers in terms of activation in the inferior frontal gyrus. The DLT was introduced as a complementary tool to MR mapping for language dominance assessment, providing information on perceptual language processing located in superior temporal cortices. The overall agreement of lateralization assessment between the two techniques was 97.1%. Conflicting results were found in one subject, and diverging indices in ten further subjects. Increasing age, non-familial sinistrality, and a non-dominant writing hand were identified as the main factors explaining the observed mismatch between the two techniques. This finding stresses the concept of an intrahemispheric distribution of language function that is obviously associated with certain behavioral characteristics.

“…Its diagnostic yield and safety for children and adults has been proved for almost every aspect of cerebrovascular pathology [22][23][24][25][26][27][28][29] . The role of superselective angiography for the evaluation of newly formed collaterals after revascularization procedures in children with moyamoya, as well as its safety despite catheterization of the vasospasm-prone middle meningeal and temporal arteries or of the small-calibre anterior choroidal artery for an endovascular approach to distal aneurysms, was also reported by other groups [30][31][32][33][34] .…”

The angioarchitecture of the so-called moyamoya vessels in children has not been explicitly analyzed. We aimed to investigate the precise anatomy of the vascular anastomotic networks in patients with childhood moyamoya disease. Six children diagnosed with moyamoya disease for the first time underwent an angiographic investigation with selective and superselective injections. We recorded the arterial branches feeding the moyamoya anastomotic networks, their connections and the recipient vessels. Depending on the level of the steno-occlusive lesion, the feeding vessels included the medial striate arteries, the perforators of the choroidal segment of the carotid, the uncal artery, the medial and lateral branches of the intraventricular segment of the anterior choroidal artery, perforators of the communicating segment, the superior hypophyseal arteries, the prechiasmal branches of the ophthalmic artery, the ethmoidal arteries and the dural branches of the cavernous carotid. Through connections, which are described, the recipient vessels were the lateral striate arteries and the middle cerebral, the medial striate arteries and the anterior cerebral, medullary arteries around the ventricular system, anterior temporal branches of the middle cerebral, orbitofrontal and frontopolar branches of the anterior cerebral, as well as other cortical branches of the anterior and middle cerebral territories. The use of high quality selective and superselective angiography enabled us to clearly demonstrate for the first time aspects of the microangiographic anatomy of the moyamoya anastomotic network previously only vaguely or incompletely described.
