introduction: based on the previous studies, we know that the hemispheric lateralization defects, increase the probability of psychological disorders. we also know that dominant limb is controlled by dominant hemisphere and limb preference is used as an indicator for hemisphere dominance. in this study we attempted to explore the hemispheric dominance by the use of three limbs (hand, foot and e...

OBJECTIVES Language function is mainly located within the left hemisphere of the brain, especially in right-handed subjects. However, functional MRI (fMRI) has demonstrated changes of language organization in patients with left-sided perisylvian lesions to the right hemisphere. Because intracerebral lesions can impair fMRI, this study was designed to investigate human language plasticity with a...

Right hemisphere dominance for visuo-spatial attention is characteristically observed in most right-handed individuals. This dominance has been attributed to both an anatomically larger right fronto-parietal network and the existence of asymmetric parietal interhemispheric connections. Previously it has been demonstrated that interhemispheric conflict, which induces left hemisphere inhibition, ...

background: n-terminal pro-brain natriuretic peptide (nt-probnp) is a sensitive biomarker for the detection of asymptomatic left ventricular (lv) dysfunction. since β-thalassemia major patients suffer from early diastolic dysfunction due to iron deposition of chronic blood transfusion, we tried to evaluate the correlation between the serum nt-probnp level and the severity of lv diastolic dysfun...

Recent neuroimaging studies support the view that a left-lateralized brain network is crucial for language development in children. However, no previous studies have demonstrated a clear link between lateralized brain functional network and language performance in preschool children. Magnetoencephalography (MEG) is a noninvasive brain imaging technique and is a practical neuroimaging method for...

The purpose of this study was to determine the dominance preferences of physical educators and the impact the profiles can have on pedagogical knowledge in the teaching/learning environment. Participants completed a self-assessment of dominant preferences survey in the areas of the brain hemisphere, eye, ear, hand and foot preference. Chi-square and cross-tab analysis were used to analyze the d...

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...

the aim of this research was to compare brain quadrant dominance between athletic and non-athletic students. for this purpose, 199 university students participating in sport olympiad summer 1391 were selected as the athletic sample and 162 students as the non-athletic samples using simple random sampling method. the hermann brain dominance instrument (hbdi) was used for data collection. the res...

Traditional neuropsychology employs visual half-field (VHF) experiments to assess cerebral language dominance. This approach is based on the assumption that left cerebral dominance for language leads to faster and more accurate recognition of words in the right visual half-field (RVF) than in the left visual half-field (LVF) during tachistoscopic presentation. Information in the RVF is directly...

Left-hemispheric language dominance has been suggested by observations in patients with brain damages as early as the 19th century, and has since been confirmed by modern behavioural and brain imaging techniques. Nevertheless, most of these studies have been conducted in small samples with predominantly Anglo-American background, thus limiting generalization and possible differences between cul...
