The mechanisms of this success are yet to be fully understood. It is commonly agreed that while speech is lateralized mostly to the left hemisphere (for right-handed and most left-handed individuals), some speech functionality is also distributed in the right hemisphere. MIT is thought to stimulate these right language areas through the activation of music processing areas also in the right hemisphere Similarly, the rhythmic tapping of the left hand stimulates the right sensorimotor cortex in order to further engage the right hemisphere in language production. Overall, by stimulating the right hemisphere during language tasks, therapists hope to decrease dependence on the left hemisphere for language production.
