Akira Nakashima, Takefumi Moriuchi, Daiki Matsuda, Takashi Hasegawa, Jirou Nakamura, Kimika Anan, Katsuya Satoh, Tomotaka Suzuki, Toshio Higashi, Kenichi Sugawara,

Application of continuous repetition of motor imagery can improve the performance of exercise tasks. However, there is a lack of more detailed neurophysiological evidence to support the formulation of clear standards for interventions using motor imagery. Moreover, identification of motor imagery intervention time is necessary because it exhibits possible central ... Read more >>
