Human subjects play mind games

Researchers at Washington University in St. Louis have placed an electrocorticographic (ECoG) grid atop patients’ brains to gather motor signals that enable patients to play a computer game using only the signals from their brains.
The breakthrough is a step toward building biomedical devices that can control artificial limbs, some day, for instance, enabling the disabled to move a prosthetic arm or leg by thinking about it.
The ECoG method is orders of magnitude faster to learn than EEG.
