From Touchpad To Thought-pad

An anonymous reader wrote with a story saying "Move over, touchpad screens: New research funded in part by the National Institutes of Health shows that it is possible to manipulate complex visual images on a computer screen using only the mind. The study, published in Nature, found that when research subjects had their brains connected to a computer displaying two merged images, they could force the computer to display one of the images and discard the other. The signals transmitted from each subject's brain to the computer were derived from just a handful of brain cells."

"The signals transmitted from each subject's brain to the computer were derived from just a handful of brain cells"

This seems like the same amount of brain cells to do just about anything, except maybe winning a spelling contest at a Tea-party rally.
