Studies with patients suffering from lesions in the corpus callosum reveal that the posterior portion of this structure plays a crucial role in the interaction of syntactic and prosodic information during language processing. Allen Human Brain Atlas available from:. Suprasegmental prosodic information overtly available in the acoustic language input is processed predominantly in a temporo-frontal network in the right hemisphere associated with a clear electrophysiological marker. Electrophysiological measures indicate that within these networks syntactic processes of local structure building precede the assignment of grammatical and semantic relations in a sentence. ![]() These networks have been substantiated both by functional as well as by structural connectivity data. Networks involving the temporal cortex and the inferior frontal cortex with a clear left lateralization were shown to support syntactic processes, whereas less lateralized temporo-frontal networks subserve semantic processes. Different brain regions in the left and right hemisphere have been identified to support particular language functions. The knowledge about its neurobiological basis has been increased considerably over the past decades. Language processing is a trait of human species.
