It is possible to manipulate complex visual images on a computer screen using only the mind. The study, published in Nature, found that when subjects had their brains connected to a PC displaying two merged images, they could force the computer to display one of the images and discard the other. The signal transmitted from each subject's brain to the computer were derived from just a handful of brain cells. The study reflects progress in the development of brain-computer interfaces (BCIs), devices that allow people to control computers or other devices with their thoughts. BCIs hold promise for helping paralysed individuals to communicate or control prosthetic limbs.
