Experimental sequence used during calibration of the brain-computer interface. The participant sat comfortably in front of a computer monitor that provided cues indicating when to attempt specific movements with his paralyzed hand. These movements included precision pinch, hand closing (fist), lateral pinch, and hand opening and were presented at random.
