University of Utah neurosurgeon Paul A. House, shown here in an operating room, led a study showing that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don't penetrate it. The tiny electrodes should last longer than those that poke into brain tissue, and may extend the useful lives of experimental devices to help amputees and paralyzed people operate robotic limbs or use thoughts to control a computer.
