In order to construct a Brain Machine Interface (BMI) system, it is critical to elucidate a characteristic of brain activities in relation to internal motor representation, namely motor imagery. This study investigates the nature of transfer of motor imagery from one (i.e. left) side to the other (i.e. right) side of the visual field by means of showing enhanced activities of electroencephalographic (EEG) signals. We found that motor-related activities during motor imagery task transferred across visual fields with reversing goggles. Furthermore, the activity persisted after taking off the goggles, demonstrating that visuomotor learning of motor imagery completed.
