The brains of people who have stuttered since childhood show evidence of rewiring, with the right side taking on tasks generally handled by the left. A new study, in which participants tapped their fingers in time with sounds, shows that this rewiring extends beyond speech.
Research so far indicates that stutterers have problems linking what they hear with what they say, according to Martin Sommer, a study researcher and neurologist at the Department of Clinical Neurophysiology, Georg-August- University of Goettingen, Germany in Germany. He compared stuttering speech to music from a disorganized orchestra.
“The question is not single elements themselves, not the instruments. They all know their parts. The question is how to activate them in a coordinated and well-timed fashion,” Sommer said.
