摘要：

Bilabial, alveolar and velar sounds are produced at different locations around the oral cavity. fMRI was used to localize cortical representation of articulation in seven healthy subjects during repetitive lip and vertical tongue movements as well as repetitive articulation of \pa\ (bilabial), \ta\ (alveolar), \ka\ (velar consonants) and a combination of all three in \pataka\. Centers of gravity (COG) analysis of fMRI activation in the primary motor (MI) and sensory cortex (SI) revealed \pa\- adjacent to lip representation and \ta\- articulation to tongue representation. The articulation of \pataka\ showed an activation pattern with a combination of the Mo MI/SI-components and additional activation in the supplementary motor area.
