Cognitive and/or sensorimotor stimulations of the brain induce increases in cerebral blood flow that are usually associated with increased metabolic demand. We tested the hypothesis that changes in arterial blood pressure (ABP) and arterial Pco(2) also take place during brain activation protocols designed to induce hemispheric lateralization, leading to a pressure-autoregulatory response in add...

Art is a product of human creativity; it is a superior skill that can be learned by study, practice and observation. Modern neuroscience and neuroimaging enable study of the processes during artistic performance. Creative people have less marked hemispheric dominance. It was found that the right hemisphere is specialized for metaphoric thinking, playfulness, solution finding and synthesizing, i...

Infants' speech perception abilities change through the first year of life, from broad sensitivity to a wide range of speech contrasts to becoming more finely attuned to their native language. What remains unclear, however, is how this perceptual change relates to brain responses to native language contrasts in terms of the functional specialization of the left and right hemispheres. Here, to e...

Many surgeons have right hand dominance as in the normal population. Right hand dominance may cause difficulties depending on the position of the patient and the surgeon position according to the patient during surgical treatment. Even when the patient is operated on in the neutral position, there are some challenges. In spinal surgery, the difficulties faced by surgeons are in the phase of spi...

BACKGROUND AND PURPOSE Determining language dominance with fMRI is challenging in patients with brain tumor, particularly in cases of suspected atypical language representation. Supratentorial activation patterns must be interpreted with great care when the tumor is in or near the presumed language areas, where tumor tissue or mass effect can lead to false-negative fMRI results. In this study, ...

Brain hemispheric dominance and study habits are student level variables and are of great significance concerning their scholastic achievement. Analysis with interaction effect of the Brain hemispheric dominance and study habits with academic achievement in mathematics was ended up in this study and discovers that there is a significant interactional relationship between academic achievement in...

Introduction. The recent emphasis on learning strategies and their effects on success has promoted researchers from different disciplines to carry out research in this regard. Methods. This paper reports the results of the study performed on 41 students, randomly selected out of 120 students, in an attempt to find out their learning style preferences. It has replicated the study presented by ...

Human brain mapping allows the systematic assessment of interindividual differences in functional brain anatomy. Functional transcranial Doppler sonography (fTCD) is an imaging tool that allows for fast and mobile assessment of hemispheric lateralization of task-related brain activation. It is ideal to screen large cohorts of subjects. The goal of the present study was to investigate whether fT...

Social cues conveyed by the human face, such as eye gaze direction, are evaluated even before they are consciously perceived. While there is substantial individual variability in such evaluation, its neural basis is unknown. Here we asked whether individual differences in preconscious evaluation of social face traits were associated with local variability in brain structure. Adult human partici...
