| Abstract(in English) | In our daily life, we frequently perform coordinated movements using right and left hands and fingers. Such movements are important to explore coordinated control mechanisms between hemispheres. In this study, subjects perform two patterns forefinger movements (in-phase and anti-phase movements). In Exp.1, to explore the cross talk information between inter-finger control systems, we gradually changed the motion visual-feedback gain or the force field gain of left finger movement. We observed a strong inter-finger cooperation in the in-phase movements. And we found a significant cross talk effect in the kinematics of forefinger movements. In Exp.2, subjects perform in-phase movement tasks using sudden change of these gains with different distance between right and left hands. We found that the change in the right finger's movement amplitude is stronger in the 'near' condition than in the 'far' condition. |
