Using your brain in games might be bad for you

Although Sixaxis or the WiiMote may seem like the latest trend in game controllers, scientists are researching what would seem like the ultimate controller: the human brain. Researchers have been studying BCIs or brain-computer interfaces as a way for people with disabilities to interact with their environment through a computer. By measuring the electrical activity in the brain, sensors attached to the head can amplify the signals and input the information into a computer where it gets translated into commands that can control a game or move stuff, like a robot arm or a wheelchair.
