Training setup for control of neural prosthesis using brain-computer interface

Reports on the development of experimental setup and initial results for control of an artificial wrist through brain computer interface (BCI). As a first step towards the development of thought controlled prosthesis, the authors created a system that allows a user to move an animated wrist on a computer screen in the up and down directions. In their experiments, the authors used surface electroencephalogram (EEG) signals above sensory-motor areas, while the subjects were attempting to use only mental activities to modulate their EEG signals resulting in desired movements of the animated wrist. In the authors' initial trials with two subjects, both demonstrated the ability to move the animated wrist as desired. These results provide a good basis for developing more enhanced wrist controls such as turn, grasp and release.
