A new brain-computer interface (BCI) has enabled paralyzed people to move a cursor across a computer screen, not only by merely thinking about it, but also, with no invasive surgery.

This can be considered a step towards developing noninvasive mentally-wired artificial limbs.

Scientists have always believed only invasive brain-computer interfaces involving direct brain implantation of electrodes could be sensitive enough to allow the full range of movements and attitudes needed to operate a robotic arm or limb.

Jonathan Wolpaw and Dennis McFarland at the Wadsworth Center in Albany, New York have now demonstrated a method of attaching electrodes to the scalp which is at least as effective as some internally implanted electrodes.
