How singing may help stroke victims recover speech

Patients who lose the ability to speak after suffering a stroke may be able to regain their speech using a novel technique that effectively reroutes the way the brain processes language, according to research presented this past weekend at a meeting of the American Association for the Advancement of Science. The technique, known as Musical Intonation Therapy, was first developed in the 1970s, when doctors realized that stroke patients who had lost the ability to speak could still sing, the Wall Street Journal reports. Yet it hasn’t been widely used—or fully understood—in the years since. This new study, led by a Harvard neurologist Dr. Gottfried Schlaug, may go some way toward changing that.

A new study from researchers at Beth Deaconess Medical Center and Harvard Medical School suggests that tone-deafness may be the result of a missing neural connection. By using a brain imaging technique that allows them to examine the links between the right temporal and frontal lobes, the scientists compared the neural connectivity of 10 tone-deaf [...]
