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
