| Outline of Final Research Achievements |
We performed a motor adaptation experiment in which a novel dynamical environment (force field) was imposed on the hand while participants performed arm reaching movements. We simultaneously applied transcranial direct current stimulation (tDCS) to the left sensorimotor cortex and the rightward and leftward force field was always associated with the anodal and cathodal tDCS, respectively. When the participants tried to perform the reaching movement after sufficient amount of the training, the application of anodal and cathodal tDCS automatically activated the motor memory that was associated with the polarity. This result indicates that the motor memory of a movement is formed and retrieved according to the movement representation in the brain.
