In most people the left hemisphere of the brain is dominant for language. Because of the increased incidence of atypical right-hemispheric language in left-handed neurological patients, a systematic association between handedness and dominance has long been suspected. To clarify the relationship between handedness and language dominance in healthy subjects, we measured lateralization directly b...

H. Immordino-Yang, 2007 ), I showed that Nico (missing his right cerebral hemisphere) and Brooke (missing his left) had compensated...

Age-related neurodegenerative and neurochemical changes are thought to underlie decline in motor and cognitive functions, but compensatory processes in cortical and subcortical function may allow maintenance of performance level in some people. Our objective was to investigate age-related changes in the motor system of the human brain using functional MRI. Twenty six right handed volunteers wer...

background: there are conficting reports regarding the association between coronary artery disease (cad) and mild cognitive  impairment (mci). volumetric magnetic resonance imaging (mri) investigations have been considered as an objective biomarker for  mci. in this study, we determined the relationship between the regional brain volumes and the extent of cad in mci patients and  cognitively no...

Does a conflict between inborn motor preferences and educational standards during childhood impact the structure of the adult human brain? To examine this issue, we acquired high-resolution T1-weighted magnetic resonance scans of the whole brain in adult "converted" left-handers who had been forced as children to become dextral writers. Analysis of sulcal surfaces revealed that consistent right...

Previous functional MRI and brain electrophysiology studies have studied the left-right differences during the tapping tasks and found that the activation of left hemisphere was more significant than that of right hemisphere. In this study, we wanted to delineate this lateralization phenomenon not only in the execution phase but also in other processing phases, such as early visual, pre-executi...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

Background The role of the microbiota-gut-brain axis in Parkinson’s disease (PD) has received increasing attention. Although gender differences are known to an essential epidemiology and clinical course PD, there no studies on sex specificity development progression PD. Methods Fresh fecal samples from 24 PD patients (13 males, 11 females) were collected for metagenomic sequencing. composition ...
