Singing 'rewires' damaged brains in stroke patients

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.

In this audio clip, we hear a stroke patient working with researchers. The patient is unable to speak the words to the familiar song Happy Birthday, but he is still able to sing it.
