Abnormal functional lateralization and activity of language brain areas in typical specific language impairment (developmental dysphasia).

Atypical functional lateralization and specialization for language have been proposed to account for developmental language disorders, yet results from functional neuroimaging studies are sparse and inconsistent. This functional magnetic resonance imaging study compared children with a specific subtype of specific language impairment affecting structural language (n = 21), to a matched group of...

Specific language impairment as systemic developmental disorders

Specific Language Impairment (SLI) is a disorder characterised by slow, abnormal language development. Most children with this disorder do not present any other cognitive or neurological deficits. There are many different pathological developmental profiles and switches from one profile to another often occur. An alternative would be to consider SLI as a generic name covering three developmenta...

Using functional magnetic resonance imaging (fMRI) to explore brain function: cortical representations of language critical areas

Pre-operative determination of the dominant hemisphere for speech and speech associated sensory and motor regions has been of great interest for the neurological surgeons. This dilemma has been of at most importance, but difficult to achieve, requiring either invasive (Wada test) or non-invasive methods (Brain Mapping). In the present study we have employed functional Magnetic Resonance Imaging...

Co-localisation of abnormal brain structure and function in specific language impairment

We assessed the relationship between brain structure and function in 10 individuals with specific language impairment (SLI), compared to six unaffected siblings, and 16 unrelated control participants with typical language. Voxel-based morphometry indicated that grey matter in the SLI group, relative to controls, was increased in the left inferior frontal cortex and decreased in the right caudat...
