| Outline of Final Research Achievements |
With the objective to assist the development of congenital upper limb hypoplasia infant’s body perception, Artificial Bodypart was designed to enhance donning and thumb-sucking of the Bodypart from early postnatal period. Glove type HTV silicon elastomer foam Bodyparts were prototyped. Adolescent subjects voluntary stimulated their perioral skin with the Bodyparts and hedonic scale were instrumented of the prefrontal cortex activity. Differentiations of Oxygenated hemoglobin, OxyHb, were measured with optical topography and distributions of facial temperature were measured with dermal thermography. The result of OxyHb increase by an average of 9.95 m(mol/l)mm during and after stimulation, and the results of 2 channel groups' prefrontal cortex activity measurement were significantly different between without and with stimulation to the perioral skin. Furthermore, the difference of alinasal temperature reduction was significant when glabellar and perioral skin temperature were not.

| Academic Significance and Societal Importance of the Research Achievements |
学術的意義としては，本研究成果として製作したHTVシリコーンエラストマー製人工ボディパーツについて，それによる随意運動触覚刺激が成人健常者において脳活動の変化と生理反応に変化を生じさせることを確認し，今後は，幼児において同傾向を生じさせるかを調査するとともに，継続使用による効果を調査する点が挙げられる．また，社会的意義としては、製作したHTVシリコーンエラストマー製人工ボディパーツはユーザが幼児であることから，本研究による実験から得られたエビデンスは対専門家だけではなく対保護者にも理解しやすいかたちで示すことができるよう予め設計して実験を行っている点が挙げられる．
