The right hemisphere is predominantly involved in tasks associated with spatial attention. However, left hemispheric dominance for spatial attention can be found in healthy individuals, and both spatial attention and language can be lateralized to the same hemisphere. Little is known about the underlying regional distribution of neural activation in these 'atypical' individuals. Previously a la...

the purpose of the research was to examine the relationship between educational administrators' brain quadrant dominance and the level of their performance effectiveness. by using stratified-random sampling method, 103 managers and 412 teachers were selected as the study sample; they were recruited from high schools in mashhad in 2008-2009 academic year. herrmann brain dominance instrument, wit...

IMPORTANCE A thorough understanding of why we hold a cell phone to a particular ear may be of importance when studying the impact of cell phone safety. OBJECTIVE To determine if there is an obvious association between sidedness of cell phone use and auditory hemispheric dominance (AHD) or language hemispheric dominance (LHD). It is known that 70% to 95% of the population are right-handed, and...

Visuospatial functions are typically lateralized to the right cerebral hemisphere, giving rise to a left visual field advantage in visual half-field tasks. In a first study we investigated whether this is also true for symmetry detection off fixation. Twenty right-handed participants with left hemisphere speech dominance took part in a visual half-field experiment requiring them to judge the sy...

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 best established lateralized cerebral function is speech production, with the majority of the population having left hemisphere dominance. An important question is how to best assess the laterality of this function. Neuroimaging techniques such as functional Magnetic Resonance Imaging (fMRI) are increasingly used in clinical settings to replace the invasive Wada-test. We evaluated the usefu...

The present study sought to explore the relationship between Iranian EFL teachers' brain dominance, teaching experience and their teaching style. The study population consisted of all EFL teachers of high schools in Shiraz holding a B.A degree, with the sample consisting of 100 participants recruited through convenience sampling. The study employed a descriptive correlational design. To collect...

Handedness and brain asymmetry are widely regarded as unique to humans, and associated with complementary functions such as a left-brain specialization for language and logic and a right-brain specialization for creativity and intuition. In fact, asymmetries are widespread among animals, and support the gradual evolution of asymmetrical functions such as language and tool use. Handedness and br...

AIM The brain venous drainage dominance is generally divided into three groups; right or left dominance and co-dominance. There is no study in the literature examining the link between brain venous drainage and aneurysm formation or rupture. Our aim was to evaluate the association between venous dominancy, aneurysm formation and rupture. MATERIAL AND METHODS Eighty-six patients, who underwent...
