摘要: • A pattern of correlative changes in lateralization individuals with known or suspected brain injury recently has been advanced as the syndrome pathological left-handedness (PLH). This syndrome, which is believed to be caused by an early left-sided cerebral lesion, may include asymmetric motor and/or trophic on right side a body part addition higher-level cognitive processing abilities. Several clinical case studies have provided support for such syndrome. Despite their importance, are unfortunately subject inherent biases selection. The present study was therefore designed evaluate PLH systematic fashion using large number brain-injured and normal subjects. incidence each putative elements investigated. results suggest that traits atypical speech representation, impairment nondominant hand, hypoplasia foot salient features discussed reference diagnostic implications.
