| Outline of Final Research Achievements |
The purpose of this study was to elucidate the brain activity by which transcranial direct current stimulation (tDCS) affects the functions of movement and postural maintenance, and to determine the relationship between kinematic and posture. We compared the subjective postural vertical (SPV) perception before and after stimulation of the supplementary motor area(SMA) with tDCS, suggesting that tDCS has an effective influence on the SPV vertical perception in postural control. The results of this study suggest that tDCS has an effective effect on the vertical cognition of SPV, which is a part of the postural control.

今回、経頭蓋直流電気刺激（tDCS）を用いて、一時的に脳活動を変化させたときの機序を明らかにするために、補足運動野と小脳に焦点を当てて研究を実施した。姿勢制御のなかで垂直性の認知は重要となるが、その認知に補足運動野の役割が明らかになった。さらには、予測的姿勢制御に及ぼす影響に関して補足運動野または小脳を刺激する研究を行ったが、重心動揺に関して明らかな差はなかった。今回の結果から、補足運動野にtDCSの刺激をすることで垂直性の認知に関して改善させる可能性があることを示唆した。
