16-Microelectrode Grid

Caption: An array of 16 microelectrodes -- known as a microECoG grid -- is arranged in a four-by-four array and shown next to a US quarter-dollar coin with a Utah state design on its "tail" side. University of Utah researchers placed two such microelectrode grids over speech areas of a patient's brain and used them to decode brain signals into words. The technology someday might help severely paralyzed patients "speak" with their thoughts, which would be converted into a computerized voice.
