Cerebral specialization between the left and right hemisphere is a fundamental concept in neuroscience. Left–right brain asymmetries of macroscopic structures or functions in human brain are well characterized (Toga & Thompson, 2003). For example, the left hemisphere is dominant for language and logical processing, whereas the right hemisphere prevails in spatial cognition. The brain is also la...

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...

Lateralized brain regions subserve functions such as language and visuospatial processing. It has been conjectured that individuals may be left-brain dominant or right-brain dominant based on personality and cognitive style, but neuroimaging data has not provided clear evidence whether such phenotypic differences in the strength of left-dominant or right-dominant networks exist. We evaluated wh...

abstract neurofibromatosis 1 (nf1) an autosomal dominant disorder, is the most common of the phakomatoses (neurocutaneous syndromes) and has a variety of localized or systemic manifestations and the classic systemic lesions include neurofibromas and more specifically, plexiform neurofibromas. a 60-year-old female presented with a progressively increasing swelling over left side of forehead and ...

Research supports the premise that various mRthematical topics can be categorized as being performed better by the left or right brain hemisphere. This study examined the effect of left and right brain hemispheric lateralization exercises upon course grades in two sections of Analysis I (beginning calculus for mathematics/science majors) at a small liberal arts college for black women. In one s...

Both the degree to which the left-hemisphere is specialized for language and the relative ability of the right-hemisphere to subserve language function are underspecified. The present study sought to identify whether the right-frontal fMRI activation seen in a number of case studies in patients with left-sided brain lesions exists as a group-level trend in patients with left-frontal tumors. It ...

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...

In typical right-handed patients both apraxia and aphasia are caused by damage to the left hemisphere, which also controls the dominant right hand. In left-handed subjects the lateralities of language and of control of the dominant hand can dissociate. This permits disentangling the association of apraxia with aphasia from that with handedness. Pantomime of tool use, actual tool use and imitati...
