Pitt/UPMC team describes findings from BCI study in spinal cord-injured man in PLoS One
Date:2/8/2013

red neural signals that were sensed by the electrodes. Distinct signal patterns for particular observed movements were used to guide the up and down motion of a ball on a computer screen. Soon after mastering movement of the ball in two dimensions, namely up/down and right/left, he was able to also move it in/out with accuracy on a 3-dimensional display.

"During the learning process, the computer helped Tim hit his target smoothly by restricting how far off course the ball could wander," Dr. Wang said. "We gradually took off the 'training wheels,' as we called it, and he was soon doing the tasks by himself with 100 percent brain control."

The robot arm was developed by Johns Hopkins University's Applied Physics Laboratory. Currently, Jan Scheuermann, of Whitehall, Pa., is testing another BCI technology at Pitt/UPMC.
