[extropy-chat] 'Thinking Cap' Controls Computer in New Experiment

[Giu1i0 Pri5c0]

Yahoo News: Four people were able to control a computer using their
thoughts and an electrode-studded "thinking cap," U.S. researchers
reported on Monday.
 They said their set-up could someday be adapted to help disabled
people operate a motorized wheelchair or artificial limb.
While experiments have allowed a monkey to control a computer with its
thoughts, electrodes were implanted into the animal's brain. This
experiment, reported in the Proceedings of the National Academy of
Sciences (news - web sites), required no surgery and no implants.
"The results show that people can learn to use scalp-recorded
electroencephalogram rhythms to control rapid and accurate movement of
a cursor in two dimensions,"
"The impressive noninvasive multidimensional control achieved in the
present study suggests that a noninvasive brain control interface
could support clinically useful operation of a robotic arm, a
motorized wheelchair, or a neuroprosthesis,"
