Research Abstract	丹治は前補足運動野に特徴的な活動を見出した。すなわち行おうとしていた運動の企画段階で、それを変更する時点に対応して、特異的に活動する細胞が顕著に見出した。柴崎は随伴陰性変動CNV課題を用いて正常者に行動選択を行わせた時の脳電位の頭皮上分布を検討した。刺激に基づいて行動決定をさせると前頭部寄りに大きな脳電位が出現することが解った。彦坂は、運動の学習と記憶の機序を調べるために、サルを用いて脳の局所の機能を遮断する実験を行った。その結果、運動順序をあたらしく学習し、それを手続きの記憶として獲得するために、大脳皮質の前補足運動野pre-SMAが重要な役割をもっているのに対し、その順序手続きの記憶を長期的に蓄え、利用するためには小脳(特に歯状核)が必要であることが示唆された。川人は、運動制御のためには脳の中に制御対象や外界の内部モデルをもつ必要があることを主張してきたが、本年度腕を対象に、運動中の腕のかたさを計る装置(平行リンク磁気浮上型マニピュランダム)を用いて、運動中の腕はやわらかいことを示すことに成功した。木村は、大脳基底核が順序運動の学習や記憶に関与する仕組みを明らかにするために、サルの一側の黒質線条体ドーパミン系を選択的に破壊することによって、順序運動の学習と記憶の能力にどのような影響を及ぼすかを調べた。その結果、黒質線条体ドーパミン系は、順序運動の学習と記憶想起の過程に強く関与することが明らかとなった。笠井は、頭の角速度と視線角速度の関係に個人差があるか、トレーニングによりVORゲインを低下させられるかを調べた結果、VORゲインの低下の仕方には個人差が明確にあることが明らかとなった。臼井は、視覚初期過程のメカニズムの解明のために、網膜神経細胞の2次元モデルの効率的なシミュレーション環境を実現した。
