Laterality Differences in Cerebellar-Motor Cortex Connectivity.
Lateralization of function is an important organizational feature of the motor system. Each effector is predominantly controlled by the contralateral cerebral cortex and the ipsilateral cerebellum. Transcranial magnetic stimulation studies have revealed hemispheric differences in the stimulation strength required to evoke a muscle response from the primary motor cortex (M1), with the dominant h...
متن کاملL2-Proficiency-Dependent Laterality Shift in Structural Connectivity of Brain Language Pathways
Diffusion tensor imaging (DTI) and a longitudinal language learning approach were applied to investigate the relationship between the achieved second language (L2) proficiency during L2 learning and the reorganization of structural connectivity between core language areas. Language proficiency tests and DTI scans were obtained from German students before and after they completed an intensive 6-...
متن کاملWhy does language laterality index vary?
Introduction A strong motivation for clinical use of functional magnetic resonance imaging (fMRI) is to determine functional language lateralisation prior to neurosurgery. Problems remain however with this approach: Agreement is not complete between fMRI lateralisation of language and the Wada test (1). Further, it has been seen that the laterality index (LI) measured with fMRI can vary with an...
متن کاملFunctional connectivity changes in the language network during stroke recovery
OBJECTIVE Several neuroimaging studies have examined language reorganization in stroke patients with aphasia. However, few studies have examined language reorganization in stroke patients without aphasia. Here, we investigated functional connectivity (FC) changes after stroke in the language network using resting-state fMRI and performance on a verbal fluency (VF) task in patients without clini...
متن کاملAltered functional connectivity of the language network in ASD: Role of classical language areas and cerebellum☆
The development of language, social interaction and communicative skills is remarkably different in the child with autism spectrum disorder (ASD). Atypical brain connectivity has frequently been reported in this patient population. However, the neural correlates underlying their disrupted language development and functioning are still poorly understood. Using resting state fMRI, we investigated...
