3-D Hand Movement Experimental Setup (image) Society for Neuroscience Share Print E-Mail Caption The reaching apparatus used to study the finger paths from a center button to eight other buttons in random order. While volunteers touched the buttons, researchers recorded their brain signals and hand motions. Afterward, the researchers attempted to decode the signals and reconstruct the 3-D hand movements.
