- 2011-2012年度科学研究費助成事業(科学研究費補助金(若手研究(B))研究成果報告書 課題番号：23700608 研究代表者：塗木淳夫(鹿児島大学・大学院理工学研究科・助教)視覚的運動予測と触覚的運動予測に基づく運動予測の特徴を明らかにするために、脳活動を混乱させる非侵襲性手技である経頭蓋磁気刺激法（TMS）、触覚提示ロボット（把持力計測：GF）、バーチャル3次元空間を用いて研究を行った。その結果、視覚情報と運動学習・機能を研究するために有用で斬新な3Dバーチャル触力覚提示システムを開発することに成功した。さらに、開発したシステムを用いて、視覚的運動予測に基づく運動学習における運動皮質の興奮活動と運動力学的な把持運動の特性に関する基礎的な知見を得ることができた。We studied whether a conflict between vision and haptics in the previous lift has an effect on the force planning of the next lift using virtual objects. We quantified the grip force (GF) rate peak as a behavioral read-out of force planning and used transcranial magnetic stimulation (TMS) to probe corticospinal excitability (CSE). We successfully developed the 3D VR haptic system which allow to study motor learning and function. Furthermore, we showed that GF rate peaks were significantly changed after trial of a visuo-haptic conflict and CSE followed the same trend as the GF rate. Our results show that the motor system is capable to bias the sensorimotor memory by rapidly learning a new size-weight relationship.
