Computer circuit built from brain cells

Weizmann Institute of Science researchers have developed a way to control the growth pattern of neurons to build reliable circuits using neurons rather than wires.
They suggest that brain-cell logic circuits could serve as intermediaries between computers and the nervous system, allowing the paralyzed to control robot arms or learn to talk again without a drop-off in performance when scar tissue coats their electrodes.
