The brain speaks: Scientists decode words from brain signals

The brain speaks: Scientists decode words from brain signals: "This magnetic resonance image (MRI) of an epileptic patient's brain is superimposed with the locations of two kinds of electrodes: conventional ECoG electrodes (yellow) to help locate the source of his seizures so surgeons could operate to prevent them, and two grids (red) of 16 experimental microECoG electrodes used to read speech signals from the brain."
