Mouth Movement - Non Stutterer

Having been programmed by the inferior pre-motor area (speech preparation) and triggered by the supplementary motor area (movement release), this area (the primary-motor mouth area) directly controls the muscular movements of speech. In non-stutterers, the activations are stronger on the left side of the brain.
