| Research Abstract |
While the position of the phalangeal joint and the configuration of the muscles/tendons at the joint were numerically different among the subjects, the function of the muscles/tendons was common among them. While the roles of the muscles/tendons were different among the subjects in the manipulation of the fine fingertip force, the roles were able to be classified into some cases. The classification was explained using the tendon driven models developed on the MRI data. In the manipulation of the fine fingertip force, the manipulability of the finger depends on the finger posture. The brain activity controlling the fingertip changes in order to adjust the muscle forces to the variation of the manipulability of the finger. The conclusions indicate the possibility that the neural mechanism of the motor learning depends on the characteristics of the muscles/tendons, i. e. the controlled object. This could provide new insights for research into motor nerves physiology.
