Reorganization of eloquent cortex enables rescue of language functions in patients who sustain brain injury. Individuals with left-sided, early-onset focal epilepsy often show atypical (i.e. bilateral or right-sided) language dominance. Surprisingly, many patients fail to show such interhemispheric shift of language despite having major epileptogenic lesions in close proximity to eloquent corte...

Recent fMRI and fTCD studies have found that functional modules for aspects of language, praxis, visuo-spatial functioning, while typically left, left right hemispheric respectively, frequently show atypical lateralisation. Studies with increasing numbers participants are finding module combinations, which here termed cerebral polymorphisms—qualitatively different lateral organisations cognitiv...

Intermanual coordination assessed by alternating finger tapping and finger-tapping asymmetry were investigated in 105 healthy right- and 105 left-handers and related to handedness, familial sinistrality and lateral preferences (in hand-clasping, arm-folding and eyedness). Compared to right-handers, left-handers with less pronounced left-hand preferences (Subgroup B) showed higher values in inte...

Recent ®ndings raised evidence that in early-onset left temporal lobe epilepsy, women show greater functional plasticity for verbal memory than men. In particular, women with lesionor epilepsy-driven atypical language dominance show an advantage over men. The question asked in this study was whether there is evidence of sexand language dominance-dependent late, i.e. adult age, plasticity for ve...

Response inhibition is defined as the capacity to adequately withdraw pre-planned responses. It has been shown that individuals with deficits in inhibiting pre-planned responses tend to display more aggressive behaviour. The prefrontal cortex is involved in both, response inhibition and aggression. While response inhibition is mostly associated with predominantly right prefrontal activity, the ...

Neonatal and adult strokes are more common in the left than right cerebral hemisphere middle arterial territory, extracranial intracranial vessels systematically left-dominant. The aim of research reported here was to determine whether asymmetric vascular ground plan found adults present healthy term neonates (n = 97). A new transcranial Doppler ultrasonography dual-view scanning protocol, with...

Most people are right-handed and left-cerebrally dominant for speech, leading historically to the general notion of left-hemispheric dominance, and more recently to genetic models proposing a single lateralizing gene. This hypothetical gene can account for higher incidence of right-handers in those with left cerebral dominance for speech. It remains unclear how this dominance relates to the rig...

Research suggests that gestures influence cognitive processes, but the exact mechanism is not clear. Additionally, it has been shown that when a linguistic task (metaphor explanation) involves the right brain hemisphere, the left hand becomes more gesturally active. We hypothesized that gestures with a particular hand activate cognitive processes in the contralateral hemisphere. We examined whe...

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...
