BACKGROUND AND PURPOSE While functional MR imaging and other techniques have contributed to our knowledge of functional brain localization, these methods have not been extensively applied to the complex and incompletely understood task of swallowing. We used functional MR imaging to investigate motor cortex activity during swallowing in healthy human adults. METHODS Eight subjects were imaged...

This paper considers and analyses the idea propounded by Iain McGilchrist that foundation of Western rationalism is dominance left side brain this occurred first in ancient Greece. It argues transformation Greece, as part a more widespread sometimes termed Axial Age, was, at least part, connected to emergence literacy which transformed workings human brain. was not uniform took different forms ...

45 Human hands are architecturally symmetrical, yet distinctly different in their functional abilities. This seemingly unique human tendency to use the right hand rather than the left for fine motor function is observed in ~90% of the human population. The remaining ~10% are atypical (i.e. left-handers). In addition to clearly visible hand dominance in humans, there are other behavioural latera...

Two studies examined self-infiltration (as indexed by a tendency toward false self-ascription of assigned tasks) and its relationship to the activation of the two hemispheres of the human brain. Unilateral muscle contractions of each hand were performed by participants to activate the contralateral hemisphere and influence self-infiltration (confusing assigned tasks as self-selected in memory)....

INTRODUCTION AND OBJECTIVES The long-term prognostic significance of coronary artery dominance pattern in patients with ST-segment elevation myocardial infarction is poorly characterized. We investigated the prognosis of such patients according to whether they had right dominance, left dominance, or codominance. METHODS This was a retrospective study of 767 patients, who were admitted to hosp...

Conclusions The result suggested that mother tongue Japanese and non- mother tongue Japanese differ in their pattern of brain dominance when listening to sounds from the natural world-in particular, insect sounds. These results reveal significant support for previous findings from Tsunoda (in 1970). Objectives This study concentrates on listeners who show clear evidence of a 'speech' brain vs a...

Background: To localize cortical speech areas, methods such as fMRI are commonly used, but the Wada test can also determine whether a region is critical to particular task. We report case of left-handed patient with left frontal tumour in whom language paradigms produced both and right Broca’s Wernicke’s areas. Methods: All imaging used 3 Tesla Siemens Skyra scanner. The performed five tasks: w...

The aim of the present study was to explore auditory cortical oscillation properties in developmental dyslexia. We recorded cortical activity in 17 dyslexic participants and 15 matched controls using simultaneous EEG and fMRI during passive viewing of an audiovisual movie. We compared the distribution of brain oscillations in the delta, theta and gamma ranges over left and right auditory cortic...

Brain activation of 11 healthy right-handed subjects was studied with magnetoencephalography to estimate individual hemispheric dominance for speech sounds. The auditory stimuli comprised binaurally presented Finnish vowels, tones, and piano notes in groups of two or four stimuli. The subjects were required to detect whether the first and the last item in a group were the same. In the left hemi...
