| Research Abstract |
In this study, we have developed a bidirectional brain-machine interface to operate a prosthetic arm with tactile sensor using the electrocorticogram(ECoG) recorded by the electrodes implanted on human sensorimotor cortices. Some severely paralyzed patients due to stroke or trauma were shown to be able to operate the prosthetic arm only using their ECoG signals by imaging some movements of their paralyzed limbs. The patients operated the prosthetic arm to manipulate some objects by grasping and releasing. Furthermore, we have developed a prosthetic arm to be controlled by signals of magnetoencephalogram(MEG).
