Abstract (in Japanese) (See Japanese page) 
(in English) Since a human has a large number of muscles, it is thought that controlling the enormous degrees of freedom is difficult. However, the human achieves the movement skillfully and it is not known how the central nervous system controls and coordinates many degrees of freedom. One of the major hypothesis to solve this problem is the mechanism of muscle synergies. In this study, we focused on the extraction of the muscle synergies in a grasping task. At first, we confirmed the feature extraction from EMG using principal component analysis. After that,we examined a neural network model for extracting the correlated information between different kinds of information. As a result, we confiremed that the neural network model could extract the muscle synergies in the grasping task from the hand shape and EMG signal.
