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...

Holistic processing (HP) and hemispheric lateralization are both expertise markers of object recognition. For example, expertise in face and sub-ordinate object perception is shown to be associated with HP and stronger right hemispheric lateralization. However, HP is modulated by experiences of selective attention to parts such as writing experiences of Chinese characters (Tso, Au, & Hsiao, 201...

Sex, stimulus material and attention condition have previously been related to global advantage (faster responses to global targets than to local targets), as well as lateralization during global-local processing. It is presumed that the lateralization of brain functions is either related to the inhibitory influence of the dominant on the non-dominant hemisphere or reduced excitation between he...

The mechanisms underlying cerebral lateralization of language are poorly understood. Asymmetries in the size of hemispheric regions and other factors have been suggested as possible underlying causal factors, and the corpus callosum (interhemispheric connections) has also been postulated to play a role. To examine these issues, we created a neural model consisting of paired cerebral hemispheric...

Language lateralization is one of the most prominent examples of functional hemispheric asymmetries. Previous studies indicate a significant contribution of factors not related to DNA sequence variation on the development of language lateralization, but the molecular processes underlying this relation are unclear. The Brandler-Paracchini model of hemispheric asymmetries assumes that genes invol...

It is widely believed that advantages of hemispheric asymmetries originated in better cognitive processing, hence it is often implied that the relationship between hemispheric asymmetry and cognitive performance is linearly positive: the higher the degree of lateralization in a specific cognitive domain, the better the performance in a corresponding task. Yet, the empirical evidence for this no...

BACKGROUND AND PURPOSE The influence of stroke lateralization on functional and cardiovascular outcome after stroke is not well established. We evaluated the influence of hemispheric lateralization among patients enrolled in prospective acute stroke trials. METHODS We obtained data from the VISTA database for acute stroke trials which reported lateralization. Baseline data, cardiac adverse ev...

The present study is to determine the effects of background noise on the hemispheric lateralization in music processing by exposing 14 subjects to four different auditory environments: music segments only, noise segments only, music + noise segments, and the entire music interfered by noise segments. The hemodynamic responses in both hemispheres caused by the perception of music in 10 different...

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...

Language function in the right-hemispheric homologues of Broca's and Wernicke's areas does not only correlate with left-handedness or pathology, but occurs naturally in right-handed healthy subjects as well. In the current study, two non-invasive methods of assessing language lateralization are correlated with behavioral results in order to link hemispheric dominance to language ability in heal...
