Abstract

Neuropsychological research indicates no absolute dominance of the left cerebral hemisphere for language communication in right-handed persons. Since the right hemisphere of the brain is involved in many important aspects of communication, lesions in this hemisphere may be the cause of various language disorders. Experiments discussed in the paper evidence that the right cerebral hemisphere is co-responsible for the lexical-semantic processing, discourse comprehension and production, as well as for linguistic and emotional prosody. It is relatively less important for the representation of the phonetic and syntactic language systems.
