Document Summary
When considering the relationship between brain and language, our knowledge is based entirely on findings in man. Some authors even argue that language is exclusively a human attribute, so that no experiments on animals could be relevant. The bulk of our knowledge on language disorders has been derived from studies and autopsies on patients who have suffered brain damage as a result of occlusion of blood vessels. Aphasia: the disorders of language resulting from damage to the brain. The criterion of an aphasia disorder is that the verbal output a person"s speech - must be linguistically incorrect. This would be due to weakness of the muscles of articulation, which may still be used normally in non-linguistic activities. Aphasia disorders could occur without impairment of other cognitive functions, making them the first demonstrations of the fact that selective damage to the brain could affect one class of learned behaviour while sparing others.
