| Research Abstract |
The overall goal of this study was to elucidate the biological background of speech, and this study was aimed to investigate the mechanisms of generation, impairment and plasticity of speech in cleft lip and palate. Following results were obtained ; 1) Magnetic resonance imaging(MRI) movie was newly developed to investigate the peripheral mechanism for articulation, 2) significant interactions between peripheral articulatory movement(obtained using MRI movie) and brain activation pattern(obtained using fMRI) were found, 3) the cortical activation pattern by tongue sensation was dependent on the side preference of mastication, 4) brain activation pattern in auditory association area for glottal-stop perception was different from normal articulation in healthy subjects.
