Teaching stroke patients to sing "rewires" their brains, helping them recover their speech, say scientists.
By singing, patients use a different area of the brain from the area involved in speech.
If a person's "speech centre" is damaged by a stroke, they can learn to use their "singing centre" instead.
Researchers presented these findings at the annual meeting of the American Association for the Advancement of Science (AAAS) in San Diego.
http://news.bbc.co.uk/1/hi/sci/tech/8526699.stmMy wife died 20 years ago - aggressive tumour over the speech centre. The symptom was that lost all nouns - adjectives etc were just fine. However she only lost them in english - she still had the whole lot in Spanish which she learned as a second language. So I assume foreign languages are also processed by another part of the brain.
