Outline of Final Research Achievements

Brain activation for vocal was found in superior frontal gyrus, superior and middle temporal gyrus, medial frontal gyrus, angular gyrus, supramarginal gyrus, and cingulate gyrus. The image training method was same regions as brain activation for vocal. Then, we make a trial of with/without phonation into tube training for brain activates using fMRI. The finding results suggested that the phonation into tube training specific activation regions had superior frontal gyrus, middle temporal gyrus, and cingulate gyrus and this method proved for image training. A large difference occurred at the tube diameter in activation region in the frontal lobe, the best tube diameter was 5 mm in the phonation into tube training on the fMRI.
