ECoG and microECoG Placement

Caption: 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. University of Utah scientists used the microelectrodes to translate brain signals into words -- a step toward devices that would let severely paralyzed people speak.
