Disrupted functional connectivity affects resting state based language lateralization
Pre-operative assessment of language localization and lateralization is critical to preserving brain function after lesion or epileptogenic tissue resection. Task fMRI (t-fMRI) has been extensively and reliably used to this end, but resting state fMRI (rs-fMRI) is emerging as an alternative pre-operative brain mapping method that is independent of a patient's ability to comply with a task. We s...
متن کاملSECT ION 1 Asymmetry, handedness and language lateralization
The physiology and behavior of all animals are strongly dependent on the large-scale structure of the body plan. While many animals are fundamentally bilaterally symmetric, vertebrates and many invertebrates exhibit a consistently oriented left–right (LR) asymmetry of the heart, viscera, and brain. The biased asymmetry of LR patterning is distinct from environmentally determined asymmetry or th...
متن کاملThe ontogenesis of language lateralization and its relation to handedness.
Dominance of the left hemisphere for many aspects of speech production and perception is one of the best known examples of functional hemispheric asymmetries in the human brain. Classic theories about its ontogenesis assume that it is determined by the same ontogenetic factors as handedness because the two traits are correlated to some extent. However, the strength of this correlation depends o...
متن کاملSex differences in handedness, asymmetry of the planum temporale and functional language lateralization.
Many studies have investigated sex differences in language lateralization. Despite the large number of investigations, controversy about the presence of sex differences in lateralization remains. This study aims to provide a complete overview of sex differences in several reflections of language lateralization: handedness, asymmetry of the Planum Temporale (PT) and functional lateralization of ...
متن کاملAbnormal lateralization of functional connectivity between language and default mode regions in autism
BACKGROUND Lateralization of brain structure and function occurs in typical development, and abnormal lateralization is present in various neuropsychiatric disorders. Autism is characterized by a lack of left lateralization in structure and function of regions involved in language, such as Broca and Wernicke areas. METHODS Using functional connectivity magnetic resonance imaging from a large ...
