Previous studies on brain reorganisation in aphasia, including studies on the influence of lexical therapy, revealed that both the left and the right brain hemispheres contribute to recovery in aphasia. However, language is usually lateralised to the left hemisphere, raising questions about the role of the right hemisphere in intact language processing and aphasia recovery. The present overview informs about the division of labour between both hemispheres and the communicative-linguistic abilities of the right hemisphere. As a conclusion, the right hemisphere can only partly compensate for left hemisphere loss due to its restricted linguistic capabilities. However, its specialisation in sentence, text and context processing as well as its cognitive resources can at least assist intact language processing. It remains unresolved to what extent the right hemisphere can acquire linguistic knowledge and contribute processing strategies after left hemisphere damage to improve language performance.
