Many linguists are interested in linguistic deficits (i.e. aphasia) that arise after brain injury. By investigating them, we can potentially infer something about how language is organised in people without brain damage – both which components comprise language and where the different components are located in the brain. We hope to answer questions like: Is there a difference between grammar and lexicon? Are language comprehension and language production located in different brain areas? How do we access the meanings of words, and are words with similar meanings also close to each other in the brain? The problem with a lot of research on aphasia, however, is that it has primarily focused on European languages that are structurally very similar.
