Apraxia in left-handers.
In typical right-handed patients both apraxia and aphasia are caused by damage to the left hemisphere, which also controls the dominant right hand. In left-handed subjects the lateralities of language and of control of the dominant hand can dissociate. This permits disentangling the association of apraxia with aphasia from that with handedness. Pantomime of tool use, actual tool use and imitati...
متن کاملSwitching handedness: fMRI study of hand motor control in right-handers, left-handers and converted left-handers.
The purpose of this study was to investigate the differences in the brain organization of motor control in left- and right-handers and to study whether early left-to-right handwriting switch changes the cortical representation of finger movements in the left and right hemispheres. Echo-planar MR imaging was performed in 52 subjects: consistent right-handers (RH), consistent left-handers (LH), a...
متن کاملDo left-handers have increased mortality?
To study the association between handedness and mortality, we evaluated the experience of a Swedish population-based cohort comprising 48,964 conscripts age 18-21 years in 1969-1970. We linked this cohort to the Cause-of-Death Register through 1989. Hand preference was measured by a simple question regarding handedness; to confirm the answer, the conscript held a dummy rifle while an observer r...
متن کاملAuditory space perception in left- and right-handers.
Several studies have shown that handedness has an impact on visual spatial abilities. Here we investigated the effect of laterality on auditory space perception. Participants (33 right-handers, 20 left-handers) completed two tasks of sound localization. In a dark, anechoic, and sound-proof room, sound stimuli (broadband noise) were presented via 21 loudspeakers mounted horizontally (from 80 deg...
متن کاملHeart rate and blood pressure responses of left-handers and right-handers to autonomic stressors.
We hypothesized that cerebral dominance may contribute to differences in cardio-vascular responses of right-handers (RH) and left-handers (LH) to autonomic stressors. We tested this hypothesis by exposing 14 RH, and 14 LH males to category I tests in which the hand and cerebral cortex were involved in performing the test viz.--i) Cold pressor test (CPT), ii) Handgrip dynamometry (HGD) and; cate...
