Singing and talking are treated differently by our brains. That's shown by new experiments. You need all sorts of brain functions for talking: you need to think of what you want to say, then you need to formulate it in words and then you need to use the muscles in your mouth and throat to make the sounds. It's possible to disable a selected area of the brain using magnets so that you can, for example, still formulate worlds, but no longer pronounce them. It's also possible to turn of certain sections that allows you to sing just fine, but when the same words have to be spoken you no longer can.

If we can turn off certain areas of the brain, will we start to concentrate more on the areas that are still being used? That might speed up the learning process considerably.
