PolloDiablo writes "Researchers at Washington University in St. Louis have reported success with recording the signals a brain sends out to the other parts of the body and using them to play a game. The subjects had to move a cursor towards a target in a one-dimensional environment without using any bodypart, just pure brainpower. One subject had a success rate of 100%. This could prove a breakthrough in the use of prosthetics. The next step is repeating the same test in a 2-dimensional environment. Similar tests have been done with monkeys before but never with humans."
