Auditory and visual stimuli in language mapping by functional MRI: is it modality specific?

Human language is a complex process that involves specialized subsystems with certain modularity of organization. Mapping of language processing is of interest because of its social importance and clinical applications. Therefore, the purpose of the present study was to assess language processing us...
