Mind Games 

From Washington University in St. Louis:
For the first time in humans, a team headed by researchers at Washington University in St. Louis has placed an electronic grid atop patients' brains to gather motor signals that enable patients to play a computer game using only the signals from their brains.

WUSTL researchers have shown it possible to play video games with your brain, not your hands.

The use of a grid atop the brain to record brain surface signals is a brain-machine interface technique that uses electrocorticographic (ECoG) activity-data taken invasively right from the brain surface. It is an alternative to the status quo, used frequently studying humans, called electroencephalographic activity (EEG) - data taken non-invasively by electrodes outside the brain on the skull.
